Zinc 5-(4-hydroxyphenyl)-10,15,20-triphenylporphyrin was synthesized. Then the covalently modified nanocomposite was gained through the esterification between the oxidized multi-walled carbon nanotube (MWNT) and the zincporphyrin. Noncovalently modified with the zincporphyrin, the nanocomposites was gotten through π-π pileup. The morphology of the nanocomposites was studied by transmission electron microscopy (TEM), and the structure of resultant products was characterized by FT-IR spectra. The comparison of the two kinds of nanocomposites was studied by UV absorption, fluorescence spectroscopy and TGA. Moreover, the noncovalent functionalization provides a higher fluorescence quenching than the covalent functionalization. The weight percentage of metalloporphyrin attached to the MWNT through π-π pileup is higher.
