摘　　要：烷氧基锌酞菁的二聚性质研究＊丁西明熊国祥许慧君＊＊（中国科学院感光化学研究所，北京１００１０１）关键词酞菁，聚集，聚集数，聚集平衡常数四吡咯环的金属络合物（如叶绿素、脱镁叶绿素等）是植物中构成光合作用反应中心的重要化合物，它们通过光诱导电子转移过程产...he aggregation properties of zinc phthalocyanines substituted with alkoxy chain of various length were studied. It is believed that the driving force of aggregation is hydrophobic interaction. The critical solvent composition for aggregation cΦ and critical aggregate concentration CAC as well as average aggregate number(n) and aggregate constants (K) were determined. It was found that the phthalocyanine with straight long alkoxy chains prefer to form dimers in THFH2O mixed solvent, the longer the alkoxy chain, the stronger the aggregation tendency with higher aggregation constant. 
