Fluorescent photochromes of diarylethene series: synthesis and properties

The research data in the field of fluorescent photochromic di(het)arylethenes published over the last decade are summarized. The characteristics of these compounds significant for their application in the design of molecular optical memory systems and photocontrolled switches are considered. The main types of diarylethenes and methods for their synthesis are described, and the correlations between structure and spectral properties, in particular, fluorescence characteristics are analyzed. Considerable attention is given to the means for endowing diarylethenes with fluorescence properties as one of the most promising methods for data readout from molecular information carriers. The bibliography includes 203 references.
