Multi-walled carbon nanotubes （MWNTs） were covalently and non-covalently functionalized with tetra- （4-hydroxylphenyl） porphyrin （THPPH2） and its complexes （ZnTHPP） forming dispersible nanohybrids in organic solution. The morphology of the nanohybrids was observed with transmission electron microscopy. The structure of the product was characterized by FT-IR, UV-Vis spectrophotometer, fluorescence spectroscopy and thermogravim- etric analysis. The photo-induced electron-transfer process of the nanohybrids in organic solution was also revealed.
