Photochemical Phase Transition Behavior of Supramolecular Polymer with a Triazine Core

Abstract

A photoresponsive azobenzene derivative having a triazine core moiety was prepared. Self-assembly of the triazine containing azobenzene derivative (Azo-TA) in aqueous dimethylsulfoxide and N,N-dimethylformamide afforded fibrous supramolecular polymers. Melting and regeneration of the supramolecular polymer were observed with alternative 365 nm UV and visible light irradiation by reversible cis-trans isomerization of azobenzene moieties.
