Research Abstract

Novel chiral phthalocyanine dyes with swastika geometry have been synthesized and their photophysical properties have been investigated in order to develop organic molecules having intense circular dichroism (CD) and magnetic circular dichroism (MCD) signals. Such a molecule is expected to exhibit magneto-chiral dichroism, which is regared as a new magneto-optical effect. Some chiral isomers of the phthalocyanine derivatives were separated by using HPLC techniques, and measured CD and MCD spectra. The absolute configuration of the chiral isomers was determined by quantum chemical calculations.
