PORPHYRIN-PHOSPHORIC ACID DERIVATIVE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a water-soluble porphyrin derivative and to provide a method for producing the derivative. SOLUTION: The porphyrin derivative is represented by formula (I) äwherein, Rs denote each a hydrogen atom or a 1-18C alkyl group; R1s denote each a hydrogen atom or a group represented by formula (II) (wherein, R2s denote each a hydrogen atom, a 1-6C alkyl group or a phenyl group which may be substituted with a halogen, a 1-4C alkyl group or a nitro group)}.
