系列尾式卟啉化合物的合成及光电性质研究

Synthesis and Optoelectronic Properties of Tailed Porphyrins

卟啉化合物是一类具有共面的18π电子共轭大环体系化合物,其卟啉环上可引入各类取代基,并能与多种金属配位。设计合成了3种带有不同取代基的甲基丙烯酰氧基修饰的尾式卟啉配体,并以有机金属盐法、苯甲腈法合成了与其对应的金属锌、铂配合物。通过红外光谱、核磁共振氢谱和UV-Vis光谱等对卟啉化合物的结构进行表征,证实了所合成的化合物为目标产物,并系统研究了卟啉化合物在二氯甲烷溶剂中的荧光性质与电化学性质。实验结果表明,通过改变卟啉苯环上取代基的种类及中心金属配位,可以对卟啉化合物的光学性质和电化学性质产生明显的影响。

Porphyrins are a kind of coplanar 18πelectron conjugated macrocyclic compounds.Various substituents could be introduced into the porphyrin ring and various metal ions could coordinate with porphyrin ligand.Three tailed porphyrin ligands with different substituents were synthesized.The corresponding Zinc and Platinum complexes were synthesized by organometallic salt method and benzonitrile method.The structures of porphyrin compounds were confirmed by IR,~1HNMR and UV-Vis spectra,and the fluorescence and electrochemical properties of the compounds dissolved in dichloromethane were investigated.The optical and electrochemical properties of porphyrin compounds can be significantly affected by changing the kinds of substituents and the central metal coordination.
