| 摘 要： | 本文报道了邻位和对位桥联苯丙氨酸锌双卟啉的合成，考查了双卟啉的分子结构对诱导圆二色性的影响。结果表明，两个卟啉环之间的π－π堆积和手性激子偶合作用是影响此类双卟啉圆二色光谱的主要因素。 |

| Abstract: | L- and D-phenylalanine bridged zinc bis-porphyrin with the connecting chain at ortho and para position of two phenyl rings o,o-C2-Phe-C2-(TPP)2Zn2 and p,p-C2-Phe-C2-(TPP)2Zn2] have been synthesized and characterized. o,o-C2-Phe-C2-(TPP)2Zn2 exhibited strong induced circular dichroism (ICD). While p,p-C2-Phe-C2-(TPP)2Zn2 exhibited no significant ICD. The ICD of present complexes were mainly determined by the pi-pi interaction and chiral excition coupling between two porphyrin moieties of the molecules. Our results also indicated that the existence of chiral center in a porphyrin molecule does not mean it would surely exhibit ICD. |
