diketopyrrolopyrrole-based Schiffbase L was synthesized and its anion sensing behavior was explored. L showed exclusive response toward HSO4 − ion and also distinguished HSO4 − from other anions by color changes (from dark red to orange) and 21 fold fluorescence enhancement at 370 nm in aqueous solution (THF/H2O = 8/1, v/v). The sensing mechanism was suggested to proceed via a hydrolysis process. The results
合成了一种新的基于二酮吡咯并吡咯的席夫碱L,并探索了其阴离子传感行为。大号,发现其朝HSO独家响应4 -离子,并且还区分HSO 4 -从由颜色改变其它阴离子(从暗红色至橙色)和在水溶液中370纳米21倍的荧光增强(THF / H 2 O = 8/1, v/v)。建议传感机制通过水解过程进行。结果提供了比色和荧光分析,以选择性地检测 HSO 4 的存在-范围广泛的其他干扰阴离子。结果可能用作双比色荧光探针,用于监测生理和环境系统中的HSO 4 -水平。

synthesized as a selective fluorescent and colorimetric chemosensor for cyanide without interference from other common anions including fluoride and acetate. The spectral responses of 1 to cyanide were studied: an approximately 130 nm red shift in absorption spectra (from λmax-ab = 516 nm to λmax-ab = 646 nm and the color change from pink to indigo) and “turn-off” emission response was observed.

A new probe 1 was synthesized by incorporating an α,β-unsaturated ketone to a diketopyrrolopyrrole fluorophore. The probe exhibited a selective and sensitive response to cyanide against other anions. Addition of CN− aqueous solution to 1 resulted in a rapid color change from pink to light yellow together with a blue shift from 518 to 421 nm, while other anions did not induce any significant color change
