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)2Zn2and p,p-C2-Phe-C2-(TPP)2Zn2] have been synthesized and characterized. o,o-C2-Phe-C2-(TPP)2Zn2exhibited strong induced circular dichroism (ICD). While p,p-C2-Phe-C2-(TPP)2Zn2exhibited no significant ICD. The ICD of present complexes were mainly determined by the π-π interaction and chiral exciton 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.
