Acyl Hydrazone Functionalized Benzene-1,3,5-tricarboxamides (BTAs) for Enhanced Control over Supramolecular Polymerization

Light-responsive molecules have been extensively studied in many disciplines due to their dynamic, yet controllable behavior. In recent literature acyl hydrazones have gained attention due to their robustness, high-yielding synthesis and their tunable modularity. We describe the synthesis and characterization of acyl hydrazone functionalized benzene-1,3,5-tricarboxamide (BTA) based supramolecular polymers. The incorporated acyl hydrazones undergo light induced E to Z isomerization, which will change the arrangement of monomers in the supramolecular fibers and disassemble them.
