摘要:

设计合成了对称型菲并咪唑荧光探针PIP-ph-PIP, 并对其结构进行了表征和确认. 随着探针溶液中水体积分数的增加, 探针的聚集程度逐渐增加, 荧光强度先增强后猝灭. 荧光光谱测试结果表明, 在水相体系中探针PIP-ph-PIP能以ON-OFF-ON的方式分别对Ag+和SCN-, Cu2+和PO34 -进行连续识别, 且连续识别效果可通过裸眼比色观察, 其中对Ag+识别具有超低检出限(6.1 nmol/L). 结果表明, 探针PIP-ph-PIP可应用于活体HeLa细胞中Ag+和Cu2+的定性分析及实际水样中Ag+和Cu2+的定量检测.

Abstract:

The symmetric fluorescent probe PIP-ph-PIP based on phenanthro[9,10-d]imidazole was designed and synthesized, and its structure was characterized and confirmed. As the increasing amount of water in the solution of PIP-ph-PIP, the fluorescence intensity of PIP-ph-PIP first increased and then quenched with the gradual aggregation. The results of the fluorescence spectra indicated that the probe PIP-ph-PIP could selectively and successively recognize Ag+ and SCN-, Cu2+ and PO34 -, respectively, with an ON-OFF-ON mode in the aqueous system. Moreover, the continuous effect can be observed by the colorimetric naked eye. The probe PIP-ph-PIP offered a relatively low detection limits of 6.1 nmol/L for Ag+ ions. The probe PIP-ph-PIP was successfully applied to detect Ag+ and Cu2+ in living human cancer cells(HeLa cells) and quantitively analyze of Ag+ and Cu2+ in actual water samples.
