Abstract

The absorption spectrum of SbCl5 doped thin films of poly(2-thienylmethyl methacrylate) displays new bands in the visible region attributable to electronic transitions in the radical cation of 2,5'-disubstituted bithiophene. Apparently, radical cations of thiophene, initially generated upon doping, rapidly cross-link with neutral thiophenes on neighboring chains. The polymer has been successfully grafted with other thiophene monomers by a similar oxidative coupling reaction. The grafting of side-chain polymers with thiophene and pyrrole monomers could yield new electroactive and nonlinear optical materials.
