Abstract
5,10,15,20-tetra(4-aminophenyl)porphyrinatocopper(II) [CuTAP] was covalently linked via amide bond with SWCNTs. Notable changes in the FT-IR spectra reveal the covalent linking of the porphyrin chromophore with SWCNTs. Further, covalent functionalization was confirmed by the hypsochromic shift of this nano-hybrid in the UV-visible spectra as compared to that of pristine CuTAP. 38 % weight loss observed in the TGA due to the extent of Cu-TAP functionalization. Morphology study of this nano-hybrid reveals the tubular structure, which is retained even after covalent functionalization. SWCNT-CuTAP nano-hybrid shows the hypsochromic shift and hypochromic shift compared to reported TAP or Zn-TAP due to Cu metal ion substitution.
