Through the extensive R&D of organic light-emitting diodes (OLEDs) for more than 30 years, plenty of well-elaborated novel organic optoelectronic materials and device architectures have been extensively developed, resulting in the unique commercial utilization of OLEDs for cutting-edge smartphones, large-area TVs, and further new future display applications by taking advantage of light-weight and flexibility.

From the aspect of materials science, the creation of novel light-emitting materials in OLEDs has been the central issue aimed at high electroluminescence quantum efficiency (EQE). Starting from the development of conventional fluorescence materials (1st generation) during 1990-2000th, the room-temperature phosphorescence (2000-) (2nd generation) and thermally activated delayed fluorescence (TADF) (2012-) (3rd generation) continuously pioneered the novel possibilities of organic emitters, resulted in not only high-performance OLEDs but also enriched organic photochemistry. Recently, there have been a wide variety of studies on TADF-OLEDs because of the unlimited possibilities of TADF molecular design. Further, hyperfluorescence (HP)-OLEDs have been developed since they can realize the compatibility of high efficiency and narrow spectral width, which is ideal for practical display applications.

Here we report our recent cutting-edge HP-OLEDs demonstrating high OLED performance by optimizing host, TADF, and terminal emitter (TE) molecules1-3). In particular, we focus on the blue-emission, which can show narrow FWHM and high EL quantum yield. Blue HP-OLEDs based on two new TEs are fabricated, resulting in high external quantum efficiency (EQE) of over 20%, high color purity, and high brightness. By analyzing the transient PL characteristics of the HP-OLEDs, we found the presence of efficient FRET between TADF-assistant dopant (TADF-AD) and TE molecules. Further, transient EL analysis confirmed that a smaller EHOMO difference between TADF-AD and TE efficiently helps to decrease hole trapping inside the emitting layer, hence resulting in a lower efficiency rolloff and a longer operational device lifetime. This report provides a designing principle for a TADF and TE in HP-OLEDs with well-matched energy levels, leading to efficient FRET and no significant carrier trapping.

In his talk, Adachi will mention the importance of the charge transfer (CT) phenomenon in designing high-performance organic luminescent molecules in OLEDs. Also, CT issues play a crucial role in maximizing the device's operation. Further, he will outlook the prospect of advanced CT technologies.

Abstract.

The tremendously rapid development of additive manufacturing technologies is enabling the fabrication of a new class of advanced materials, referred to as architectured materials. In contrast to monolithic materials, architectured materials have well defined internal structures at length scales which are smaller than the overall macroscopic component, but which are much larger than the length scales traditionally associated with the microstructure (e.g. grain size, lattice constant or polymer chains). Typically, architectured materials feature a controlled internal architecture ranging from 100 µm to 100 mm, therefore bridging the gap between microstructure and component size. The design of new architectured materials can profit from the strategies followed by nature in load-bearing biological materials.

This is the context of our work, where we are focusing on introducing nature’s design principles into synthetic architectured materials using inkjet multimaterial 3D printing, with the final goal to prototype next generation materials with enhanced mechanical efficiency and multifunctionality. Architectured material contains numerous internal interfaces and we have first turned our attention on the characterization of interfaces formed during inkjet printing. In short, this fabrication method is based on the controlled deposition and curing of micrometer-sized photopolymer droplets. By combining different experimental methods we have characterized the properties and the role of internal interfaces in 3D printed multimaterial composites [1]. Ongoing work is aimed at improving the mechanical behavior and failure resistance of bimaterial attachments, based on minimal interface patterning and inspired by the insertion of the soft tendon into the much stiffer bone.

Multimaterial 3D printing has a huge potential for cost-effective manufacturing of high performance composites, with soft and stiff building blocks combined in a countless variety of arrangements and linked through interfaces. Inspired by the multilayer tube-like structure of the wood cell, we have prototyped architectured materials having stiff polymeric helix-reinforcements embedded into softer rubbery matrix. By controlling the fiber winding angle and matrix compliance, we could program the mechanical response of our structures in terms of stiffness and energy absorption. We also demonstrated that adding thin outer and inner reinforcing layers to the main helicoidal structure, with small fibrous elements oriented perpendicular to the applied load as seen in the wood cell, could lead to a huge amplification of failure strength and energy absorption of the wood-inspired structures [2]. Our work has highlighted the possibility to use 3D printing in combination with computer simulations and experimental testing to design and prototype novel synthetic materials featuring design principles of biological materials, which are replicated at higher length scales and using completely different building blocks.

Abstract.

Beyond disciplinary research and education questions, is it possible to raise more systemic horizontal concerns, regarding the major transitions: climate, ecology, energy, food and heath? Over the last decade, crises are increasingly frequent and have a tendency to pile up. They affect the way of life, the way of consumption, the way of production. Such periods of tension provide information on the significant damages caused by the different types of climatic disturbances, such as social or health crises, or the loss of biodiversity and also reveal the high level of the interdependencies underlying the current ways of life. Enough observations, data and tools are now available to understand and model the impact of these global changes on the environment, health, biodiversity and society. In the European context, the Green Deal aims at making Europe the first carbon-neutral continent; this policy aims to preserve biodiversity, reduce pollution, and promote a clean and circular economy, while making this green transition a factor of economic growth, by ensuring a fair transition. The European legislative package «Fit for 55» will establish the mechanisms for fitting to the new European ambitions in the reduction of greenhouse gas emissions (a 55% at the horizon 2030, cut-off compared to 1990 level, to reach carbon neutrality in 2050), thus requiring an acceleration of the energy, environmental, sanitary and digital transitions, the implementation of carbon sinks, and probably major systemic disruptions. Progresses in disciplinary research and innovation are able to provide many solutions. On the other hand, whereas the problems are largely systemic, the approaches of them are often led in sectoral silos. Innovations must be more and more hybrid, bringing together a broad spectrum of technologies and skills from different disciplines. Working at the interfaces of different scientific fields - life sciences, physical science, digital science, engineering science, human and social science - will contribute to boosting systemic innovations that are necessary to reach a carbon-neutral and resilient society by 2050. Under the aegis of the French Ministry of Higher Education, Research and Innovation, the five national alliances (gathering the French research organizations and universities under 5 embedding topics: energy, environment, numeric, health, human and social sciences) have produced a positioning document which reflects a common and shared vision of new directions in research, to serve the major transitions, in the emerging academic discipline of sustainability science.

The 11th of February is the UNESCO day to commemorate the International Day of Women and Girls in Science. The main aim of this celebration is to give visibility to the work of women in STEM (Science, Technology, Engineering and Mathematics). More specifically, to show female referents for children and young researchers to consider these areas as professional careers. Furthermore, due to the complexity of the issue, each year there are different discussions about the factors affecting the current situation of women in STEM in order to promote practices leading to gender equality in the scientific field.

Svetlana Samokhvalova, PhD student at the ICS, and a team of students, has organized a special event to celebrate this day. The main topic of the event is mental health.  An important subject that affects everyone, and even more in the field of science. The aim is to have as much participation as possible, from both male and female colleagues.

the program:

• 09:30 - Introductory words, by Quentin Bailleul
• 09:40 - Mental health in science, by Svetlana Samokhvalova.
• 10:20 - DEI (diversity, equity, inclusion) in academia, by Dr. Mehdi Vahdati
• 10:50 - Introducing Egal'ITI, by Dr. Laure Biniek
• 10:55 - Mental health at ICS, by Svetlana Samokhvalova
• 11:00 - Closing remarks

During the event we will discuss mental health in academia, the mental load, the COVID-19 crises and how it affects scientists and especially women in academia. The DEI (diversity, equity, inclusion) principles in science will be discussed as well. We hope to have an open discussion with the audience to what can be changed to improve mental health, and how we can influence it at the Institute level. We will also provide information on mental health professionals that work with the employees and students in the CNRS and the University of Strasbourg.

Abstract.

Everyone is talking about plastic wastes and their impact on the environment. However, it is important to resist expedient reactions, because if plastics didn't exist today, humans would invent them.
In this presentation, a polymer chemist will trace the history of plastics, and explain their structure, manufacture, and waste treatment. Plastics are a much larger family than they seem, with some "good" and some "bad" plastics whose danger comes from the fact that their global production has grown so fast that it is now unmanageable.
What are the possible solutions to the problems of certain plastics? Energy recovery, "recycling", biosourced plastics and (bio)degradable plastics are the existing and developing solutions. But wouldn't the best solution be to moderate or even regulate the production/consumption of certain plastics, or to replace them with other materials?

Abstract.
Molecular self-assembly plays a key role in the development of tailor-made materials for biomedical applications. In this regard, natural polymers, which possess inherent biocompatibility, biodegradability, and non-toxicity, and more recently peptides, whose biological properties can be tailored by the sequenced defined chemical structure, have gained increasing attention. These two kind of soft materials are able to self-assemble in a controlled manner driven by intermolecular, i.e., van der Waals, hydrogen bonding, and/or hydrophobic intramolecular forces, leading to micro- and nano-structured platforms with different functionalities. Considering that the final biological properties will be highly influenced by the physical-chemical characteristics of the engineered materials, it becomes necessary to stablish a correlation between physics, chemistry, material science, biology, and medicine for the successful biomaterial implementation. Herein the design, fabrication and characterization of different supramolecular soft materials based on natural polymers and peptides will be
presented. Besides, the incorporation of nanoparticles and specific drugs within the polymer/peptide assemblies to tune the final properties of these materials to be employed for drug delivery, magnetic hyperthermia therapies, and tissue engineering applications will also be addressed.

Abstract.
Raman spectroscopy (RS) is an effective characterization technique for the detection of wide range of analytes due to its potential to provide figure-print spectra of variety of molecules by detecting the inelastic scattering of incident photons. However, the application of this spectroscopy is limited due to very low signal to noise ratio. To overcome this drawback one can use metallic structured surfaces or noble metal nanoparticles that enhances the scattering signal by several orders of magnitude. In this case we deal with the another branch of Raman spectroscopy – Surface Enhanced Raman Scattering (SERS). The interest in this topic is increasing as novel materials are found to be efficient for signal enhancement, such as dielectrics, core-shell nanoparticles, graphene etc. In this talk I will introduce the basics of SERS and will show how the signal can be enhanced when using randomly distributed particles and assembled on a predefined template.
