The diimide of metal-[2,9or10(or 2,16or17)bis(3,4-dicarboxybenzoyl)]phthalocyanine(diPc) (where i = imide) 2 or 3 were prepared from 3,4,3′,4′-benzophenonetetracarboxylic dianhydride (BTDA) (1), phthalic anhydride (PA), urea, and metal salts such as CuCl2, CoCl2, and FeCl3 etc. at 170°C. In the case of copper, the diPc monomer 2 or 3 and the dimer 4 or 5 could be synthesized. Those copper complexes are stable to all of the chemical procedures. However, the core metals of Fe(III), Co(II), Ni(II) and Zn(II)-diPc were partially removed in the acid treatment. Metal phthalocyanine derivatives which have four carboxyl groups in the peripheral site, metal-[2,9or10(2,16or17)bis(3,4-dicarboxybenzoyl)] phthalocyanine(daPc) (a = acid) 6 or 7, were synthesized by hydrolysis of the metal-diPc. The metal-daPc are soluble in water, in aprotic solvents such as N,N′-dimethylformamide, and also in sulfuric acid. The physicochemical properties of some metal-daPc derivatives were investigated.
