中文摘要：
设计合成了一系列苯醚键相连的C60-卟啉二元化合物及其金属锌配合物：H2Por-p-C60、H2Por-m-C60、H2Por-o-C60、ZnPor-p-C60、ZnPor-m-C60和ZnPor-o-C60,通过质谱、元素分析和核磁共振氢谱对它们的结构进行了表征。基态的电子吸收光谱和电化学研究表明在这些二元体系中C60和卟啉之间存在明显的相互作用。荧光光谱研究表明卟啉单元的荧光几乎被C60单元完全淬灭,并且它们之间的连接位置对荧光淬灭的效率具有显著影响。
英文摘要：
A series of C60-porphyrin dyads,connected by phenyl ether linkage of one meso-phenyl group of the porphyrin moiety on para,meta,and ortho positions,respectively,together with their zinc complexes have been designed and synthesized.All of these compounds were characterized by means of MALDI-TOF mass spectrometry,elemental analysis,and 1H NMR.The electronic absorption spectroscopic and electrochemical studies show that there is a considerable interaction between the two chromophores in the ground state of these dyads.The fluorescence spectroscopic study reveals that the emission of porphyrin moiety is efficiently quenched by C60 moiety,and the quenching efficiency is higher when the C60 linked at the ortho position of meso-phenyl ring than that linked at para or meta positions,indicating the linkage dependence of the intramolecular interaction between the two chromophores in these dyads.
