Four unique states of the photochromic hybrid shown in the Figure can be independently addressed using light energy as the only input. This system benefits from the photochromic properties of the 1,2-dithienylcyclopentene and phenoxynaphthacenequinone scaffolds and represents the first quaternary photo-switch in which all states are thermally stable.
