Titre: Hydrazone-Based Switches and Functional Materials
For the past few years we have been developing structurally simple, easy to make, modular, and tunable hydrazone-based functional materials (e.g., switches, sensors and fluorophores).1 This presentation will deal with our recent advances with these systems, with an emphasis on newly developed photochromic compounds2 that exhibit many interesting properties, including emission ON/OFF toggling in solution (see below) and the solid-state.3 The integration of these photochromic compounds into liquid crystals4 and liquid crystalline elastomers,5 and their use in the templated-synthesis of g-cyclodextrin,6 will also be discussed.
