通过紫外光谱法、稳态和时间分辨荧光光谱法比较，研究了光诱导新型1-2代羧基芳基苄醚树枝配体周边取代酞菁锌（Ⅱ）配合物的分子内能量转移。研究结果表明：1-2代羧基芳基苄醚树枝配体周边取代酞菁锌（Ⅱ）配合物主要以单体形式存在于二甲基亚砜中；在270 nm处树枝配体吸收峰强度随着树枝代数增加而增加，因此树枝配体的光捕获能力增强；树枝代数对酞菁核的荧光特性影响显著，随着树枝代数增加，荧光寿命和荧光量子产率降低；在270 nm激发，能量从外围树枝配体（给体）传递给酞菁核心（受体），这一过程中外围树枝充当能量肼的角色，随着树枝代数增加，分子内能量转移效率增大。因此，新型羧基为端基的芳基苄醚树枝酞菁锌配合物是一类新型光捕获天线结构的化合物。

The photoinduced intra-molecular energy transfer in phthalocyanine zinc(Ⅱ) bearing poly (aryl benzyl ether) dendritic substituents with carboxylic terminal was studied by steady-state ,time-resolved fluorescence and UV/Vis spectroscopic meth-ods .The result shows that the complexes mainly existed as monomers in dimethyl sulfoxide .The light-harvesting ability of this series of dendritic phthalocyanines increased with the dendron generation under 270 nm .The effects of the dendron generation on <br> the fluorescence characteristics of phthalocyanine cores was significantly ,and the fluorescence lifetime and fluorescent quantum yield decreased with the increase of the dendron generation .Intra-molecular energy could be transferred from peripheral dendron acting as an energy hydrazine to the phthalocyanine core during a photo-induced process .With the dendrimer increasing ,the in-tra-molecular energy transfer quantum yield increased .These results obviously indicated that this series of dendritic phthalocya-nines is a king of novel compound with light-harvesting structure .
