摘要
A method for synthesizing a porphocyanine having the formula: IMAGE where each R is ethyl, comprises either: (1) treating 3,3'-4,4'-tetraethyl-5,5'-bisaminomethyl-2,2'-dipyrromethane with a 10-fold excess of DDQ or (2) treating 3,3'-4,4'-tetraethyl-5,5'-diformyl 2,2'-dipyrromethane with ammonia, followed by column chromatography purification and evaporating to dryness the eluant containing the purified product.
