The project will explore the frontier of knowledge by addressing microscopic physical and chemical phenomena at dielectric/organic interfaces, which determine the electronic behavior of OFETs. Few examples are ' orders-of-magnitude effect of the gate dielectric on the carrier mobility ' uncontrolled trapping of carriers due to specific chemical groups at the insulator surface The importance of these phenomena has been fully appreciated only very recently and the microscopic mechanisms responsible for their occurrence are unknown. They limit the performance of currently mass-produced OFETs. Through their understanding, the project will contribute to: ' generate fundamental knowledge on molecular multifunctional material and their interfacial electronic properties ' put technology in the field of plastic electronics on a firm scientific basis as it is fundamentally needed for a sustainable long-term development. ' establish the link between fundamental investigations and OFET device applications The research proposed is highly original. The influence of the gate insulator on the mobility of carriers at the dielectric/organic interface has been demonstrated recently. The intrinsic and extrinsic physical and chemical mechanisms responsible for these phenomena are not known. This project will thus focus on recently highlighted problems whose solution is needed to support long-term innovation in the field of plastic electronics. The targets of the proposed activity are well beyond the current frontier of knowledge. The identification of the dielectric/organic interface (as opposed to the organic material itself) as the sub-unit determining the characteristics of OFETs is a conceptual breakthrough, whose consequences will be explored in this project. Many aspects of the experimental techniques and material systems that will be used to investigate dielectric/organic and metal/organic interfaces are also new and put in an original perspective. In particular, our work will involve - new dynamic characterization of OFET performances, - new and powerful dielectric/organic defect characterization techniques, - nano-structured monomolecular layer organic insulators - new synthesis route (metathesis) for the development of new organic semiconductors

The catalyzed intermolecular hydroamination of alkenes and more specifically its enantioselective version is nowadays a scientific and economic challenge. Concerning the activated alkenes, the area is still little developed and applications to the synthesis of products (chiral amines) of high commercial values have not yet been reported. In the non-activated alkenes (simple olefins) version, in spite of much effort, no satisfactory results have been achieved yet. We have discovered the first catalytic systems really efficient for this type of reaction, made up from the association of Pt(II), Pt(IV) or Rh(III) salts with phosphonium halides (n-Bu4PX). These are the most performing systems ever reported for the hydroamination of ethylene by weakly basic amines and the only ones allowing the hydroamination of higher olefins. Moreover, the high regioselectivity (95 %) obtained, is favourable for the development of an enantioselective version, which remains an unexplored area of research. We have a triple objective: (a) Arrive at a complete understanding of how the two simple metal systems recently developed in our laboratory operate, by the isolation of intermediates of the catalytic cycles, mechanistic studies, and computational studies. With such knowledge in hand we will be able to design new generation catalytic systems that meet with the requirements of efficient large scale production. (b) Develop the intermolecular enantioselective hydroamination with two independent goals: to find catalytic systems of general applicability for the hydroamination of activated alkenes in order to accomplish efficient syntheses of high added value chiral amines; to accomplish the asymmetric hydroamination of non activated olefins. Ligands already existing in the two participating laboratories have the potential of yielding the first successful demonstration of feasibility. Simple modifications of the ligand environment will subsequently be guided by the acquired knowledge of the key transition state (previous objective) and by QM/MM or full QM calculations. (c) Adapt the experimental conditions in such a way that the catalyst can be efficiently separated from the reaction products, recovered and recycled without significant leaching or decomposition. This objective may also be achieved through ligand modification.

Polymers play an important role in the French nuclear power industry. They are used in many safety-related applications and in large quantities to fight corrosion and fire. However, they are less durable than steel or concrete, and their maintenance has a direct impact on the cost of energy production. According to France 2030 plan, France plan to made 2 million of electric cars by 2030. e-mobility sector is currently conducting extensive research aimed at improving the autonomy of electric vehicles (mass gain) and reinforcing the "fire" barrier. In this sense, the development of a fireproof paint could help to meet these challenges. One of the fire protection methods is the use of intumescent coatings. The novelty of this proposal is to develop an eco-friendly coating suitable for different substrates (organic and metallic) with intumescence property as fire protection for organic substrate and electric mobility applications. The interest of these multifunctional materials lies in their easy synthesis method and their inorganic and green nature (without solvent and VOC emission). Furthermore, these materials can be recycled and reused in other geopolymer formulations. The present project aims at acquiring new insights into inorganic and eco-friendly intumescent coating. To reach such a target, simultaneous research efforts are planned (i) to develop new multi-substrate intumescent coating based on geopolymer material, (ii) to develop new fire resistance tests and propose rules to validate these materials, and (iii) scale up. Following the development of a fireproof geopolymer coating, the development of applications in the nuclear field as well as in the electric transport sector will be involved. The objective is to produce, at the end of this project, 3 industrial demonstrators (TRL5) with intumescent properties such as electric boxes, battery for electric vehicle and hydrogen tanks will be proposed.
