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. Key words: porphyrin dimer; chlorin dimer, pheophorbide; purpurin; stereoisomers
