A versatile approach for creating hybrid semiconducting polymer–fullerene architectures for organic electronics†
Abstract
A novel methodology, through which fullerenes are effectively introduced directly onto semiconducting species, is presented herein. Electron accepting perfluorophenyl-quinolines either as small molecules, as homopolymers, or as random copolymers with regioregular poly(3-alkyl thiophene), have been synthesized and further employed for the preparation of hybrid materials with C60 or PCBM. More specifically, via this route one of the fluorine atoms of the perfluorophenyl ring is transformed into an azide that undergoes [3+2]-cycloaddition onto the fullerene's surface, producing 1,6-azo bridged carbon nanostructure–organic semiconducting hybrids.
