Mesomorph polyoxometalate-based hybrids materials for photonics – MESOMORPHICS

Highly nanostructured semiconducting materials displaying efficient charge transfer properties hold great promise in optoelectronics. MESOMORPHICS proposes to develop a new type of photoactive and semiconducting mesomorphic materials combining donor pi-conjugated mesogenic moieties and acceptor polyoxometalates, a class of discrete nanosized oxoclusters, within a unique molecular architecture. The antagonistic chemical nature of the charged polyoxometalate and hydrophobic donors will allow the nanosegregation of the donor/acceptor sub-units thus favouring charge transport properties. The structure-property relationship in these self-organized hybrid materials will be explored with a peculiar focus on their charge transfer ability. Combining the elaboration of original multifunctional mesomorphic systems with advanced spectroscopic experiments and analysis should open a path for exploring the influence of long-range order on exciton and hole/electron diffusion pathways.
