A new Schiff base receptor 1 was synthesized and its photophysical properties were investigated by absorption, emission and excitation techniques. Furthermore, its chromogenic and fluorogenic sensing abilities towards various metal ions were examined. Receptor 1 selectively detects Cu ion through fluorescence quenching and detection was not inhibited in the presence of other metal ions. From fluorescence titration, the limit of detection of receptor 1 as a fluorescent 'turn-off' sensor for the analysis of Cu was estimated to be 0.35 μM.
合成了一种新型席夫碱受体1，并通过吸收、发射和激发技术研究了其光物理性质。此外，还考察了其对各种金属离子的显色和荧光传感能力。受体1通过荧光猝灭选择性地检测铜离子，并且在其他金属离子存在的情况下检测不受抑制。通过荧光滴定法，估计受体1作为用于分析铜的荧光“关闭”传感器的检测限为0.35 μM。
