Synthesis and electrochemistry of a substituted phthalocyaninatozinc

The synthesis of a zinc phthalocyanine (Pc) bearing four phenoxyl substituents was described and its molecular structure was fully characterized by 1H NMR, MS, elemental analysis, UV–vis and IR, which were consistent with the proposed structure. This Pc possesses excellent solubility in polar organic solvents, such as dichloromethane and THF, and doesn't readily aggregate to the dimer. TOF-MS and elemental analysis prove its excellent purity. The compound's electrochemical redox reactions in THF occurred in the Pc ring and were quasi-reversible single-electron processes. The electrochemical reaction mechanism was proposed.
