Study on Material Properties with Synthesis and Properties of a Photochromic Diarylethene with Acetal Unit

摘要

A new unsymmetrical photochromic diarylethene with an acetal unit was synthesized and its photochromic and fluorescent properties were also investigated. The compound exhibited remarkable photochromism both in solution and PMMA film. In PMMA film, the open-ring isomer of the diarylethene 1o exhibited relatively strong fluorescence at 377 nm when excited at 372 nm. All results indicated that the acetal unit played an important role during the process of photochromic reaction for the diarylethene derivatives.
