We propose to create new light-responsive chiral hybrid photoluminescent materials capable of absorbing and emitting chiral visible radiation based on optically active chiral nanofibers and their homogeneous inclusion in multi-dimensional matrices. These nanoparticles will be created by grafting luminescent molecules onto chiral silica nanoribbons with well controlled handedness, periodicity, diameter and length. The resulting architectures will be capable of absorbing light and and emitting chiral visible radiation. By carefully controlling the adsorption and aggregation of luminophore molecules on the surface, we aim to induce controllable spectral circular polarisation. These chiral nanostructures, based on bottom-up molecular self-assembly approach, will then be incorporated in various templates in order to induce hierarchical 1, 2 and 3D organization: 1) 1D nanofibers with chiral helices aligned along the axis, based on electrospinning techniques, 2) incorporation in 2D polymer films via low-cost solution coating processes such as spraying from a dispersion in solution, 3) using these silica nanohelices as polymer cross linkers to induce gelation based on 3D network formation, or silica helices adsorped on particles, were the particles are organized to form crystal colloids. The originality of our approach is based on the use of silica nanohelices as a template for the chiral organization of the chromophores instead of previously reported organic structures which are less robust and less well defined. The robustness of the templates allows their dispersion in large range of conditions (temperature, pH, salinity, etc…). Since the chirality originates from the substrates, it allow us to use non chiral luminophores, which enhances the versatility and the richness of the molecular approach we plan to use. There are many possible applications of these systems, amongst which the most promising is the generation of Circularly Polarized Luminescent (CPL) polymer films with limited energy loss in order to improve the energy efficiency and ultimately the design the flexible optoelectronic displays. The CPLhelixCNPA project offers significant potential for generating knowledge leading to economical and ecological advances and technological innovations in the field of 3D displays as it aims at generation of CPL signals by simple and accessible luminescent molecules by the use of silica nano-helices. This project has direct relevance with the call while aiming at design of new innovative materials for the application in the field of flexible electronics based on molecular technology. Indeed, to achieve such functional architectures, molecular technologies will be crucial at all steps of the conception. The photochromic nanofibers are made from silica sol-gel transcription of nanometrically controlled molecular assemblies at room temperature using water as solvent based on molecules which are synthesized at low cost and with high yield fabrication, these parameters are all crucial for environment friendliness and greenness of the procedure. To achieve this goal, a high-quality and interdisciplinary research in the field of nanotechnology is required. The consortium created for this collaborative research shows a perfect complementarity while sharing specific or common competences between the partners. While all the partners have long been collaborating on various projects, the proposed project opens a new direction of research which requires strong collaboration of all the partners. A proposal for creating a new Laboratoire Internationale Associé (LIA) has just been accepted by CNRS. This LIA, “Chiral Nanostructures for Photonic Applications (CNPA) - Hierarchical chiral nanostructures based on molecular assemblies for light management, sensor, chiral separation and catalysis”, is structured around 10 groups from Bordeaux, Kumamoto and Kyoto Universities, and the present proposal constitutes one of the core projects.
