Rational Design of Photoresponsive Supramolecular Assemblies Based on Diarylethene

Abstract

Photochromism: Functionalization of a diarylethene derivative with π-conjugated oligomers resulted in a higher aggregation capability in the open rather than the closed form due to tunable steric hindrance of methyl groups of the diarylethene core (see scheme). Distinct aggregation abilities of the open and the closed isomers in nonpolar solvent and phototunable energy transfer between the two functional units enabled visible-light-triggered formation of fluorescent organogels.
