Abstract:

Tetra-(4-hydrazidephenyl)porphyrin and its Cu, Zn complexes were synthesized with new techniques. The covalent porphyrins-functionalized MWNTs were gained by amidation reaction between the oxidized multi-walled carbon nanotubes(MWNTs) and the hydrazide porphyrins. The non-covalent porphyrins-functionalized MWNTs were obtained through π-π pileup with tetra-(4-hydrazidephenyl)porphyrin and MWNTs. The structures of the resultant products were characterized by FTIR. Strong electronic effects between porphyrins and MWNTs were found from UV-Vis absorption and fluorescence spectroscopy. Moreover, non-covalent composites provide a higher emission quenching compared with covalent composites.
