The repetitive Diels-Alder reaction: A new approach to [60]fullerene main-chain polymers

Abstract Maindashchain polymers with incorporated [60]fullerene units are accessible by reaction of buckminsterfullerene with functionalized bis -o- quinodimethanes . Cross linking can be effectively suppressed by carefully directed admixing of a mono -o- quinodimethane . The polymer 11(n) of high molecular weight and excellent solubility, consisting of 80 [60]fullerene units on the average, is affordable. This polymer can be processed to thin amorphous films of high quality by spin coating.
