Abstract: Strong magneto chiral effects in absorption of phenylalanine bridged chiral zinc bis porphyrin O,O-C2-Phe-C2 (TPP)2Zn2 were demonstrated through the comparison of natural circular dichroism and magnetic circular dichroism spectra of enantiomers. Magneto-chiral circular dichroism spectra expressed as difference between the absorption coefficients of the left circularly polarized and right circularly polarized light are given. The observed intensive magneto chiral effect was suggested to be related with the chiral exciton coupling between two zinc porphyrin chromophores of the enantiomers.

Key words: Phenylalanine, Optically active metalloporphyrin, Magneto-chiral dichroism
