meso-Tetra(4-sulfonate sodium phenyl)porphyrin and its Zn, Cu, Mn complexes were synthesized. Porphyrins-MWNTs compounds were obtained by covalently and noncovalently methods. The structures of the resultant products were characterized by FTIR and the morphology features were investigated by transmission electron microscopy (TEM). Strong electeonic effects between porphyrins and MWNTs were found from UV-vis absorption and fluorescence spectroscopy, moreover, the noncovolant functionalization provides a higher fluourescence quenching than the covalent functionalization. The thermal gravity analysis (TGA) showed that the weight percentage of the porphyrins and its metal complexes attached to MWNTs which the noncovolant functionalization is more than convalent functionalization. The solubility of new compounds was tested, and the results show that the covalently modified complexes have good solubility and dispersion.
