Strong magneto-chiral effects in absorption of phenylalanine bridged chiral zinc bis-porphyrin O,O-C2-Phe-C2-(TPP)2Zn2were 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.
