Abstract: Novel phenylalanine bridged dimeric porphyrin was synthesized by the reaction of 5-[o-(2-bromo-1-ethoxyl)]-10,15,20-triphenylporphyrin and amino acid in DMF in the presence of phase transfer catalyst BTEACin about 10%—15% yields. Zinc complexes derived exhibit strong split induced circular dichroism(ICD) at the soret absorption region and weak single peak ICD at the Qabsorption. While the corresponding free base porphyrin exhibits no obvious ICD. L-and D-phenylalanine bridged zinc porphyrin dimer constituted pairs of enantiomers. These complexes can be used as good model compounds for the investigation of induced circular dichroism of porphyrin occurring in natural systems.
