Abstract

Visible light unlocks the π-electronic conjugation of a dithienylethene-fused p-benzoquinone derivative to cause a light-driven oxidation reaction.

Highlights

The electron accepting character of a dithienylethene-fused p-benzoquinone derivative is significantly reduced upon ring-closing isomerization
Visible light unlocks the p-electronic conjugation of the quinone so it can be utilized for a light-driven oxidation reaction
We report a light-driven oxidation reaction with a dithienylethene-fused p-benzoquinone, which unlocks the p-electronic conjugation of the quinone upon exposure to visible light

Summary

Introduction

The electron accepting character of a dithienylethene-fused p-benzoquinone derivative is significantly reduced upon ring-closing isomerization. The observed differences in absorption spectra between the ring-opening and -closing forms indicate signi cant changes in the p-electronic conjugations, there are no reports that focus on their electron accepting character and chemical reactivity.
