The monomer electronic absorption spectra of the ZnPcS2P2 (disulfonated diphthalimidomethyl phthalocyanine zinc) in 11 kinds of solvents and 5 kinds of unsubstituted metal phthalocyanines in DMF were investigated. The monomer electronic absorption spectra of some substituted phthalocyanine zinc including ZnPcS4 (tetrasulfonated phthalocyanine zinc), ZnPcS4 (tetraphthalimidomethyl phthalocyanine zinc), ZnPc(NO2)4 (tetranitro phthalocyanine zinc) and ZnPcS2P2 in the same solvent were also studied. The result showed that (1) with the strengthening of coordination ability of the solvent, the maximum absorption wavelength of ZnPcS2P2 increased slightly. (2) with the increasing of electronegativity of central ion, the maximum absorption wavelength of MPcs had a little blue shift. (3) the electron-donating substituting group caused slightly blue shift. The monomer fluorescence spectra of ZnPcS4, ZnPcP4, and ZnPcS2P2 in different solvents were determined. The result showed that (1) the electron-withdrawing substituting group caused slightly red shift of the fluorescence spectra. (2) with the strenghtening of coordination ability of the solvent, the maximum emission wavelength increased slightly. (3) the fluorescence intensity of ZnPcS2P2 in the solution which contains Cremophor EL was remarkable stronger than that in other solvents. This is an important suggest to the development of photodynamic diagnose agent. The effect of solvents, central ions and substituents on spectra were partly explained by means of the quantrum chemistry.
研究了二磺酸二邻苯二甲酰亚胺甲基酞菁锌（ZnPcS2P2）在11种溶剂中的单体电子吸收光谱以及5种未取代金属酞菁在N，N-二甲基甲酰胺（DMF）中的单体电子吸收光谱。还研究了一些取代酞菁锌，包括四磺酸酞菁锌（ZnPcS4）、四邻苯二甲酰亚胺甲基酞菁锌（ZnPcS4）、四硝基酞菁锌（ZnPc(NO2)4）和ZnPcS2P2在相同溶剂中的单体电子吸收光谱。结果表明：（1）随着溶剂配位能力的增强，ZnPcS2P2的最大吸收波长略有增加。（2）随着中心离子电负性的增加，金属酞菁（MPcs）的最大吸收波长有轻微蓝移。（3）供电子取代基导致轻微蓝移。测定了ZnPcS4、ZnPcP4和ZnPcS2P2在不同溶剂中的单体荧光光谱。结果表明：（1）吸电子取代基导致荧光光谱略有红移。（2）随着溶剂配位能力的增强，最大发射波长略有增加。（3）ZnPcS2P2在含有聚氧乙烯蓖麻油（Cremophor EL）的溶液中的荧光强度明显强于其他溶剂中的荧光强度。这对光动力诊断剂的开发具有重要意义。通过量子化学部分解释了溶剂、中心离子和取代基对光谱的影响。
