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 photoactivatable fluorophore. 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。
