realized the photo-regulation of the pericellular nanofibers formed by the enzyme-instructed self-assembly on the cell membrane. Upon light irradiation, the fluorescence of nanofibers could be turned on to monitor both enzyme-instructed self-assembly and photo-induced disassembly processes. Moreover, the cell fate could be controlled through the photo-regulation.

The pyrazoline fluorophore, generated by photoinduced tetrazole-ene cycloaddition, shows faint fluorescence in protic solvents. To suppress this fluorescence-quenching, we rationally designed a series of substituted diaryl tetrazoles at the N-side phenyl ring to produce a tetrazole-ene based photoactivatablefluorophore. Spectroscopic and cellular imaging studies demonstrated that the version of the
通过光诱导四唑-烯环加成产生的吡唑啉荧光团在质子溶剂中显示出微弱的荧光。为了抑制这种荧光猝灭,我们在 N 侧苯环上合理地设计了一系列取代的二芳基四唑,以产生基于四唑烯的可光活化荧光团。光谱和细胞成像研究表明,具有双(三氟甲基)苯取代基的荧光团具有显着增强的亮度和光稳定性。

research interest in drug chemistry and organic synthesis in recent years. Herein, we report a facile access to benzocyclic boronates through photopromoted intramolecular arylborylation of allyl aryldiazonium salts. This simple protocol features a broad scope, allowing the formation of variously functionalized borates bearing dihydrobenzofuran, dihydroindene, benzothiophene, and indoline skeletons under
