Photochromic diarylethenes bearing an intramolecular hydrogen bond in bridge moiety have been prepared. It is found that intramolecular hydrogen bonding has a great effect on both absorption and fluorescence of diarylethenes. The color change of diarylethenes in a wide range (purple, blue and green) can be achieved by simple modification of the electronic properties of substituents in bridge moiety, and fluorescent diarylethenes are also obtained when diarylethenes bear an intramolecular hydrogen bond in bridge moiety.
