Photochromic materials have attracted extensive attention due to their potential applications in photonics such as photo-switching and optical memory systems. Nondestructive readout is an important consideration to avoid interference with photochromism. Among nondestructive readout method, measuring the fluorescence changes upon photochromic reaction is promising due to its single molecule detection sensitivity. In the diarylethene system, however, the fluorescence was observed when the molecule exists in the form of open-ring isomer. We have synthesized and characterized highly fluorescent and efficient photochromic materials. We found that the fluorescence quantum yield and the photochromic properties such as fatigue property and thermal stability of the compound was significantly enhanced. These findings indicate that the disulfonyl diarylethenes are suitable materials for photon mode RW memory device based on photochromic recording and non-destructive fluorescnece read-out.
