摘要
本文对若干酞菁类化合物光敏产生O的能力作了评价.发现金属酞菁化合物的中心原子对敏化能力有很大影响,敏化能力按以下次序递降:Zn>Mg>Cu>Mn>Co>Fe.由于酞菁类化合物溶液中存在二聚体与单体间的平衡,这一平衡随着浓度、溶剂极性等条件的变化而移动,所以酞菁类化合物光敏产生O的能力也随这些条件而变化.
The ability of some metallo-phthalocyanine compounds for photo-generating singlet oxygen is studied.It was found that the central atoms in these compounds have con-siderable influence on the sensitization abilities.Their activities decrease in the order of Zn>Mg>Cu>Mn>Co>Fe.In the solution of phthalocyanine an equilibrium between monomer and dimer occurs,which can be shifted with the change of the concentration or the polarity of solvents.Therefore the abilities of phthalocyanine compounds for producing singlet oxygen may also be changed under different conditions.
