Preparation and structural characterization of a star-shaped C60HxBTPVKx copolymer

Abstract A highly soluble star-shaped C 60 H x BTPVK x copolymer, which has significantly different spectroscopic properties from both free C 60 and n -butyl-terminated poly( N -vinylcarbazole)[BTPVK], was prepared in heterogeneous medium. 13 C NMR results provided a strong convincing evidence for the covalent attachment of BTPVK arms onto the C 60 core, a versatile tecton for dendrimer chemistry [Camps, X., Schonberger, H. and Hirsch, A., Chem. Eur. J ., 1997, 3 , 561]. The characterization techniques employed are UV-VIS, FTIR, TGA, ESR, XRD and 13 C NMR spectroscopy.
