The photoswitching of photochromic bisthienylethene mixed electron donor-π-accepter (2D-π-A) type fluorescent dye with appropriate doping ratio was constructed, which showed excellent fluorescence switch “on” and “off” when the photochromic bisthienylethene undergoes ring-opening and ring-closed photoisomerization with UV and visible-light irradiation in solution and PMMA film. The erasable and rewritable photoimages on the photochromic bisthienylethene mixed 2D-π-A type fluorescent dye in PMMA were successfully demonstrated, which will provide a simple and viable method for optical data storage based photochromic fluorescent materials. These developments are crucial for fundamental research and eventual tech. application for all-photo mode high-d. optical data storage.
