摘　　要：以荧光光谱和1HNMR谱研究了驱动四苯基卟啉锌 (Ⅱ ) [Zn(TPP) ] 咪唑基尾式卟啉铁 (Ⅲ ) [Fe(p ImEPTPP)Cl]超分子自组装的配位键。研究表明 ,Fe(p ImEPTPP)Cl加入到Zn(TPP)二氯甲烷溶液引起的荧光猝灭是前者的尾端咪唑基配位到后者中心离子Zn2 + 的结果。在Zn(TPP) /Fe(p ImEPTPP)Cl体系中分别加入哌啶、咪唑和吡啶等Lewis碱后荧光光谱变化提供了配位键生成的进一步证据。Zn(TPP) /Fe(p ImEPTPP)Cl体系的1HNMR谱中的咪唑基质子化学位移的变化 。Coordination bonding driving supramolecular self-assembly of Zn(TPP) with Fe( p -ImEPTPP)Cl was investigated by fluorescence spectra and ~1H NMR. The results indicate that an obvious fluorescence quenching observed from Zn(TPP) by addition of Fe( p -ImEPTPP)Cl is due to the coordination of the terminal imidazolyl group of Fe( p -ImEQTPP)Cl to Zn^2+ of Zn(TPP). The change of fluorescence spectra of Zn(TPP) / Fe( p-ImEPTPP)Cl system by adding some Lewis bases,such as piperidine,imidazole and pyridine,as well as ~1H NMR further supported this coordination.
