一种基于香豆素的铜离子荧光探针的合成及荧光性质研究
coumarin-based fluorescent probe for Cu2+ ion: Synthesis and fluorescence property study
合成了一种新型的铜离子荧光探针CPQ。探针由香豆素和8-氨基喹啉通过哌嗪桥连而成。Cu2+能够使探针CPQ的荧光发生淬灭。室温下在甲醇和水混合溶液中的紫外和荧光性质研究发现，相对于其他金属离子，探针CPQ对Cu2+具有很高的选择性，并且探针与Cu2+作用的化学计量比为1：1，并且提出了探针分子CPQ和Cu2+相作用的可能模型。
new coumarin-based fluorescent probe named CPQ for Cu2+ ion has been developed. The probe is consist of coumarin and 8-aminoquinoline linking by piperazine. The fluorescence of CPQ can be quenched by the addiction of Cu2+. Probe CPQ shows highly selectivity to Cu2+ over other metal ions in the mixture of water and methanol as solvent at ambient temperature. A 1:1 stoichiometry was shown in the CPQ and Cu2+ complex. The binding model of CPQ and Cu2+ was also given.
