M. Berrada et al., PREPARATION AND CHARACTERIZATION OF POLY(ARYLAMINE SULFONES) AND POLY(ARYL ETHER SULFONES) CARRYING THE C61 FULLEROID PENDANT GROUP, Chemistry of materials, 6(11), 1994, pp. 2023-2025
This study described the synthesis of soluble polymers carrying fuller
oid pendant groups. The starting monomer 4,4'-difluorodiphenyl fullero
id (FPh)2C61 was synthesized and polycondensed with aromatic diamine s
ulfone to give poly(4,4'-diphenyl-C61 amines) or with aromatic dialcoh
ol sulfone to give poly(4,4'-diphenyl-C61 ethers). Polycondensation wa
s carried out in different solvents with and without catalyst. Soluble
polymers having an average molecular weight in the range M(w) = (5-20
) x 10(3) were obtained. Molecular structural characterization of mono
mer and of fullerene moiety in the polymers was achieved by NMR, infra
red, and UV-visible spectroscopies, mass spectrometry, and thermal ana
lysis.
