Efficient Photoswitching of Aryloxy‐Substituted Naphthacenequinones
It is known that peri ‐aryloxyquinones based on 5,12‐naphthacenequinone (hereinafter referred to as PANQs) undergo multiple photoswitching between the initial state and thermally stable ana ‐quinone. However, no nuclear magnetic resonance (NMR) studies of their photochromic performance have been reported previously. In this work, a series of 11 new PANQs are prepared, and their light‐induced reaction is investigated using NMR spectroscopy for the first time. The results support early observations regarding the fatigue resistance as well as thermal and chemical stability of the photoisomers of peri ‐aryloxyquinones based on naphthacenequinone.
