Synthesis and study of chlorin and porphyrin dimers with ether linkage
摘要:
Novel dimers of chlorophyll compounds (pheophorbide a, chlorin p6) and model porphyrin with ether linkage were synthesized and separated into components A and B (less and more polar). The ratio of these components was the same for all dimers and irrespective of reaction conditions. Method of dimerization through trifluoroacetoxyethylderivative gave higher yields.
