Light-actuated resorcin[4]arene cavitands
Résumé
A light-actuated resorcin[4]arene cavitand equipped with two quinone (Q) and two opposite Ru(II)-based photoredox-active walls was synthesized and investigated. The cavitand is capable of switching from an open to a contracted conformation upon reduction of the Q to the SQ radical dianion state by intramolecular photoinduced electron transfer. The molecular switch was investigated by cyclic and rotating disc voltammetry, UV-Vis-NIR spectroelectrochemistry, transient absorption, and EPR spectroscopy. This study provides the basis for the development of future photoredox switches and molecular actuating nanodevices.
