The molecular spectroscopy properties of octa-carboxylic phthalocyanine aluminum(AlC8Pc) were studied.A novel method of fluorescence quenching for the determination of Cu2+ base on near-infrared fluorochrome(NIRF) of AlC8Pc(the maximum excitation and emission wavelengths at 624nm and 698 nm) was established.The effect factors were optimized.Under the optimum conditions,(pH 4.5,AlC8Pc concentration of 5.0×10^-6 mol L^-1,reaction time of 5 min and reaction temperature at room temperature) the linear range of the calibration curve for the determination of Cu2+ is from 2.5×10^-6 mol·L^-1-3.0×10^-5 mol·L^-1,with a correlation coefficient(R) of 0.9974.The limit of detection(3σ) is 8.3×10^-7 mol·L^-1.The method was applied for the determination of Cu2+ in real water samples.
