Abstract

A supramolecular 1:1 complex of the title compounds undergoes light-induced cooperative proton-electron transfer which can be switched back by warming to 60°C. The complex (see Figure) is found to exhibit a unique from the photochromism, meaning that it could have potential in optical switching (with termal back switching) or optical data storage applications.
