Several hemicyanine dyes as fluorescence chemosensors for cyanide anions
Four hemicyanine dyes as chemosensors for cyanideanions were synthesized easily. Their photophysical properties and recognition properties for cyanideanions were investigated. The results indicate that all the dyes can recognize cyanideanions with obvious color, absorption and fluorescence change. The recognition mechanism analysis basing on in situ 1H NMR and Job plot data indicates that to the
可以轻松合成四种半氰胺染料作为氰化物阴离子的化学传感器。研究了它们的光物理性质和对氰化物阴离子的识别性质。结果表明,所有染料都能识别具有明显颜色,吸收和荧光变化的氰化物阴离子。基于原位1 H NMR和Job图数据的识别机理分析表明,对于具有羟基的化合物,识别机理为分子内氢键相互作用。但是,对于不含羟基的化合物,氰化物阴离子在共轭桥中与碳-碳双键结合,并诱导N + CH 3变成中性NCH 3。加入氰化物阴离子后,化合物的荧光几乎被淬灭。
