From Molecular Complexes to Synergic Multi-Switchable Fluorescent Solids – Mol-CoSM

The Mol-CoSM project, gathering three complementary french groups (Brest (1), Versailles (2) and Nancy (3)), deals with the design of new multifunctional complexes combining, in a synergetic way, molecular switching and fluorescence. Thus, in addition to the extensive synthetic work to the design new series of multifunctional systems, this project has three orientations: (i) the control of the fluorescence yield according to the nature of the fluorophore; (ii) the control of the switching parameters, such as the transition temperature and the cooperativity; (iii) the understanding of the electro-vibrational interactions between the fluorescent motif and the SCO center, so as to enhance the bi-functionality, to produce thermal bistability, both on the magnetic and fluorescent properties. The final objective is to propose new systems with enhanced multi-functionalities for potential applications such as new generations of magneto-optical switches and molecular multi-sensors.
