Abstract
A number of amino acid porphyrins and their zinc complexes were synthesized and characterized. Only the zinc porphyrin dimer containing a chiral amino acid bridge o,o-C 2-AA-C 2(TPP) 2Zn 2 showed significant induced circular dichroism (ICD). The observed ICD of the pres system has been proposed to arise from chiral exciton coupling interaction between two zinc porphyrins of the dimer. Our CD experimental results also indicated that the obvious Soret band ICD of porphyrin does not seem to be caused by a porphyrin-aromatic group coupled-oscillator interaction or a porphyrin-carbonyl coupling mechanism.
