Abstract

Abstract: We have synthesized and fully characterized a photochromic zinc complex with a terphenylthiazole‐based ligand with a salen‐like cavity. The solution stability of the complex was found to be greatly dependent on the state of the photochromic ligand and an interesting photo‐triggered release and uptake of zinc ions was found as well as monitored by its fluorescence. The contrasting stability difference of the zinc complex between its two isomeric states was rationalized by DFT calculations. Abstract : Photo‐responsive zinc complex : The stability of the zinc complex is reversibly switched by the light‐induced interconversion of the photochromic terthiazole‐based ligand between its two isomeric states. Moreover, such a modulation is accompanied by a simultaneous fluorescence switching, offering thereby a convenient way to monitor the reaction.
