摘要:

设计合成了一种由卟啉与二茂铁通过共价键连接的四(对-甲酰基二茂铁-3-乙氧基)苯基卟啉化合物(Fe-PH2), 采用红外光谱、核磁共振氢谱和紫外光谱等手段对其结构进行了表征, 证实所合成的为目标产物. 紫外光谱和荧光光谱结果表明, 该卟啉体系内部给受体之间在基态下存在弱的相互作用, 而在激发态下存在较强的相互作用. 电化学测试结果表明, 连接4个二茂铁基的Fe-PH2具有更丰富的氧化还原性质.

Abstract:

Porphyrins have received the considerable attention because of their electron-transfer processes, photo-physics, biological processes and catalytic behaviors. This rapid development derives from their strong delocalization of π electron and conjugated macrocycles. The control of orientation of porphyrin chromophores can play a very important role. The functions of materials are related to the molecular alignments as well as the molecular structures. There were a number of reports on tetraphenylporphyrin derivatives, but those bearing the meso-substituted p-formyl-ferrocene group have been studied very little. In this paper, a symmetrical porphyrin with p-formyl-ferrocene group tetra(p-formylester-ferrocene-3-ethoxyphenyl)phenylporphyrin, was designed and synthesized through tetra(4-hydroxy-3-ethoxyphenal) porphyrin and formyl-ferrocene in CH2Cl2. The structure of tetra(p-formylester-ferrocene-3-ethoxyphenyl) phenylporphyrin was confirmed by UV-Vis, IR and 1H NMR spectra. The UV-Vis absorption and fluorescence spectra indicated weak electronic interaction in ground state and strong electronic interaction in excited state between the ferrocene donors and the porphyrin acceptors. The cyclic voltammetry indicated that ferrocene substituents have a significant effect on the redox potentials.
