摘　　要：设计合成含有不同取代基的二茂铁卟啉化合物,用核磁共振氢谱、紫外-可见光谱和红外光谱表征其结构,并讨论取代基效应对二茂铁卟啉的荧光、电化学、Raman光谱的影响和变化规律.实验结果表明:给电子取代基使卟啉荧光光谱红移,量子产率增大,对Raman光谱的苯环振动影响较大;连接给电子取代基的卟啉更易失去电子而被氧化,连接吸电子取代基的结果相反.因此通过改变卟啉周边的取代基可调控二茂铁卟啉的光谱和电化学性能.Ferrocene porphyrins with different substituents were designed and synthesized,thier structures were characterized by 1H nuclear magnetic resonance(1H NMR),ultra-violet-visible(UV-Vis)and infra-red(IR)spectra,and the effects of substituents on fluorescence,electrochemical and Raman spectra of ferrocene porphyrins were discussed.The experimental results show that the electron donating substituents make the fluorescence spectra of porphyrin red shift,increase quantum yield,and have a great influence on the vibration of benzene ring in Raman spectrum.Porphyrins connected with electron donating substituents are more likely to lose electrons and be oxidized,while those connected with electron withdrawing substituents are on the contary.Therefore,the spectra and electrochemical properties of ferrocene porphyrins can be controlled by changing the substituents around porphyrins.
