Abstract
A diarylethene derivative with thermally irreversible photochromic reactivity and good fatigue resistance has been synthesized. The two-photon-induced fluorescence of the compound is observed by excited with 800 nm beam. The intensity of the fluorescence is found to be proportional to I1.748, where I is the incident laser intensity, and decays with the increase of irradiation time. The results show that two-photon induced nonlinear photochromic reaction was partially realized. It demonstrates that the compound is a promising candidate for two-photon 3D optical data storage.
