摘要：

Two salamo-like copper(II) complex probes, L-1-Cu2+ and L-2-Cu2+, were designed and synthesized for sensitive and efficient identification of CN-. UV spectroscopy, high resolution mass spectrometry, RGB analysis and naked eye recognition were performed to explore their recognition mechanisms. High resolution mass spectra indicated that the probes L-1-Cu2+ and L-2-Cu2+ formed complexes with CN-. The two probes could recognize CN- the naked eye and the color of the solution changed from light yellow to red. In terms of application, the contents of CN- in the environmental water samples were tested. In addition, the optimal pH ranges for probe detection of CN- were investigated by pH value measurement.
