摘要
研究了某些金属酞菁配合物在单体状态下的电子吸收光谱和荧光光谱 ,并探讨了溶剂。
The monomer electronic absorption spectra of the ZnPcS 2P 2(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 ZnPcS 4(tetrasulfonated phthalocyanine zinc),ZnPcS 4(tetraphthalimidomethyl phthalocyanine zinc),ZnPc(NO 2) 4(tetranitro phthalocyanine zinc) and ZnPcS 2P 2 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 ZnPcS 2P 2 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 ZnPcS 4,ZnPcP 4,and ZnPcS 2P 2 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 ZnPcS 2P 2 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 quanturm chemistry.
