摘　　要：酸催化下,在水-甲醇体系中,合成并分离了3种含有Push-Pull取代基的新型低对称A2B型钴(III)咔咯,其结构经1H NMR,19F NMR和HR-MS(ESI-TOF)表征。并利用光谱学和电化学方法对3种钴咔咯的电子结构进行了深入研究。结果表明:引入Push-Pull型不对称对钴(III)咔咯分子的电子结构有明显的调控作用,且随着引入基团的改变而产生显著的规律性差异,为进一步的分子设计、合成及其应用奠定基础。Three new A2B type low symmetric Co(III)corroles containing Push-Pull substituents have been synthesized and isolated through acid catalyzed process in water/methanol system.The molecular structure was characterized by 1H NMR,19F NMR and HR-MS(ESI-TOF),and the electronic structure was investigated by spectroscopy(UV-Vis and MCD)and electrochemistry(CV and DPV).It has been indicated that introduction of Push-Pull substituents to corrole macrocyclic rings result the facile modulation of electronic structure which provide useful information for future molecule design,synthesis,characterization and application.
