摘　　要：报道了一种新型芳基苄醚酞菁锌配合物:四-[3,5-(二-4-硝基苯甲氧基)-苯甲氧基]酞菁锌(Ⅱ)(简称配合物3)的合成、表征、光物理性质及其光诱导分子内能量转移.相关化合物的结构通过IR、1H NMR、ESI-MS方法进行了表征.配合物3在有机溶剂中主要以单体形式存在;在光激发下,配合物3存在分子内能量转移,转移方向从树枝配体到酞菁核,能量转移效率为65%,因此配合物3是一个高效的能量传递体系.A novel dendritic substituted phthalocyanine, tetra- [ 3, 5-di- （4-nitro benzyloxy） benzyloxy ] phthalocyanine Zinc （ II ） （compound 3 ） was synthesized and characterized. The pho- tophysieal properties and photoinduced intra-molecular energy transfer of this zinc （ ]I ） phthalocya- nine were studied by steady-state fluorescence and UV/Vis spectroscopic methods. The structure of this compound was characterized by a combination of methods including IR, 1H NMR, ESI-MS. It was found that this compound showed lower aggregation behavior and monomer spectrum in organic solvent. Energy was transferred from dendron to phthalocyanine core upon excition at 697 nm, and the energy transfer quantum yield was as high as 65%, which meant that the compound 3 was a high-efficient energy-transferring system.
