Redshifted and thermally bistable one-way quantitative hemithioindigo-derived photoswitches enabled by isomer-specific excited state intramolecular proton transfer

Abstract

We report bistable indole-containing hemithioindigos (HTIs) with one-way quantitative photoswitching properties. Supported by state-averaged CASPT2/CASSCF calculations, we propose a mechanism for the observed one-way photoswitching that involves an isomer-specific excited state intramolecular proton transfer (ESIPT). Additionally, we developed a thermally bistable oligomer-inspired bipyrrole-containing HTI, which displays large band separation and bidirectional near-quantitative photoisomerization in the near-infrared, bio-optical window.
