摘　　要：测定了6种烷氧基取代酞菁锌在不同溶剂中的电子吸收光谱.在一些溶剂(如甲苯、氯仿和二氯甲烷)中,除了存在典型的Q带吸收峰外,在其长波长一侧还可观测到一个新的吸收峰,结合对其荧光、核磁共振谱、添加强碱性溶剂(吡啶)以及对溶剂除水后的光谱的研究,证实了新产生的吸收峰与溶剂中的微量水有关,探讨了该吸收峰产生的原因.The electronic absorption spectra of six different alkoxy substituted phthalocyaninatozincs in different solvents have been determined. It is found that a new band (named as X bands) appeared at the longer wavelength side of the Q band in some solvents, such as toluene and CH,Cl,. The band is assigned to the protonation of phthalocyaninatozincs by trace water in the solvent, and it is further proved by the fluorescence spectra and H-1 NMR. By adding pyridine to the solution this X band vanishs, and by adding water to the desiccated solvent this X band recurs.
