PROBLEM TO BE SOLVED: To obtain a compound having properties of forming a triplet state of long life in a high yield and acting an efficient photosensitizer in the formation of a singlet oxygen and improving availabilities of the properties in combination with high chemical stability and proper solubility in a polar solvent such as water. SOLUTION: This compound has a structure of the formula (substituents R1, R2, R3, R4 and R5 are each independently H, an alkyl, amino, hydroxy, an alkoxy, carboxy, carboxamide, an ester, amido, sulfonato, a substituted alkyl, a substituted ester, a substituted ether or a substituted amido; M is a divalent or trivalent metal cation and n is between -5 and +5) This method for synthesizing a pentadentate extended porphyrin preferably comprises a process for synthesizing diformyltripyrrane, a process for condensing the tripyrrane with an orthoaryldiamine 1,2-diaminoalkene or a 1,2-diaminoalkane and a process for oxidizing the condensation product to form a pentadentate extended porphyrin compound. |
