Fluorescence is reversibly photoregulated in high-density random copolymers constructed from photochromic phenoxynaphthacenequinones and porphyrins (see Figure) using ring-opening metathesis polymerization. Alternating irradiation of the polymers with ultraviolet and visible light toggles the photochromic components between two isomers differing in their ability to act as electron-acceptors in a photoinduced electron-transfer process.
