Abstract
Methyl pyropheophorbide-a was used as starting material for the synthesis of phenylhydrazone and amino acid Schiff base by reactions of carbonyl group at 13-position. The maximum absorption wavelength of phenylhydrazone caused a red shift. The water-solubility of Schiff base was incremented, and the maximum absorption wavelength shifted hypsochromically. The structures of all these compounds were characterized by H NMR, MS and elemental analysis.
