Abstract:

Photoswitchable fluorescent dithienylethene is one kind of the most typical diarylethene structures. Hydrophilization of photoswitchable fluorescent dithienylethene has become one of the key factors to come true its practical applications as a fluorescence photoswitching probes. Owing to its excellent fatigue resistance and unique thermal bistability, it has been widely studied and applied. This paper reviews the development history of photoswitchable fluorescent thienylethenes, summarizes the mechanism of fluorescence photoswitching mechanisms, describes some important achievements on the foundational research about novel structures and improved properties of photoswitchable fluorescent thienylethene in recent years. We also focus on the systemic overview of the applications of photoswitchable fluorescent dithienylethylene in optical memory, non-destructive read-out, single-molecule fluorescence imaging, bio-imaging, all-optical transistors. In the end, the challenges encountered during the study of diarylethenes are analyzed. It is believable that photoswithcable fluorescent polymers based on dithienylethene is the research direction in the future. Moreover, the promising application of diarylethenes in super-resolution imaging is prospected.
