Abstract
|
Poly(styrene-r-propargyloxy styrene) with varying molecular weights is prepared by means of a nitroxide-mediated radical polymerization and a malonate is clicked to it. Fullerene C60 is reacted under Bingel conditions with the polymer and can be covalently bound to its side chains. These polymers show good solubility in common organic solvents and intense studies are performed to determine the degree of substitution with fullerenes. A loading of around 15 to 20 wt% is detected by thermogravimetric analyses (TGA). These materials might be promising as the acceptor component for donoracceptor block copolymers. Furthermore, new bromine- and organo-azide-functionalized methano fullerenes are prepared and characterized.
