Abstract:
Tetra(4-hydroxyphenyl) porphyrin(THPPH2) was synthesized by condensation of 4-hydroxybenzaldehyde and pyrrole in DMF using anhydrous AlCl3 as catalyst without neccessity to use inert gas for protection. Its nickel complex(THPPNi) and Ni meso-tetra(4-benzoxyphenyl) porphyrin(TBOPPNi), Ni meso-tetra[4-(carboxymethylenoxy)phenyl] porphyrin(TCMOPPNi) were also prepared. Their structures were ascertained by elemental analysis, visible spectrum, IR and 1H NMR measurements. The electrochemical property of TCMOPPNi has been investigated in DMSO by cyclic voltammetry and differential pulse voltammetry.
