Synthesis of Optically Active Photoresponsive Multifunctional Polymer Containing the Side-Chain Azocarbazole Chromophore

A new optically active photochronic polymeth-acrylate containing the carbazike niuettm deriving from the oyloxypropanoyloxy)ethyl]carbazolyl})diazene [(S)-MLECA] has been prepared and fully characterized with the aim to obtain a nultifunctional derivative possessing at the same time chemical moieties suitable to NLO and optical storage, to chiroptical switches, and to photorefactive and photocon ductive applications. Spectroscopic, thermal and chiroptical characterizations cleirtly indicate the occurance of dipolar interactions between chromophores and the pressence of an ordered chiral conformation of prevailing helical handedness, at least for chain segments of the macromolecules. Structure of poly[(S)-MLECA].
