Abstract

A series of dithienylethenes 1a-1d with BF₂-doped π-conjugation have been successfully developed. Upon alternating irradiation with green light and red/NIR light, they show efficient photochromism and fluorescence switching behaviors in toluene and PMMA film. Moreover, the fluorescence of 1a can be switched effectively in living cells.
