【摘要】 分别测定了四--α(2,2,4-三甲基-3-戊氧基)酞菁钯(锌)和四--α(2,4-二叔丁基苯氧基)酞菁钯(锌)配合物的紫外-可见电子吸收光谱,荧光发射光谱和单线态氧生成速率,结果表明虽然酞菁钯的中心金属离子为开壳层电子结构,但其生成单线态氧(1O2)的能力与中心金属为闭壳层结构的相应取代酞菁锌相近,这可能是与其荧光发射很弱,系间串跃很强相关。更多还原

【Abstract】 The absorption spectral properties,fluorescence spectral properties and the abilities of photo-generating singlet oxygen of four phthalocyanines,namely tetra-α-(2,2,4-trimethyl-3-pentoxy) phthalocyaninatopalladium(zinc) and tetra-α-(2,4-diterbutylphenoxy) phthalocyaninatopalladium(zinc),were determined.Experimental results show that the ability of photo-generating singlet oxygen of phthalocyaninatopalladium is similar to that of phthalocyaninatozincx,though palladium(Ⅱ) is an open shell(electron) structure and zinc(Ⅱ) is a closed shell structure.This may be concerned with a weak flourescence intensity and a strong inter-crossing transition of phthalocyaninatopalladium.更多还原
