Abstract
The present invention relates to a polymer including a fullerene core and a plurality of prepolymer units. Each of the prepolymer units is linked to a carbon atom of the core by a moiety independently selected from the group consisting of --O--(C.dbd.O)--NH--, --NH--(C.dbd.O)--NH--, --0--(C.dbd.S)--NH--, and --N--(C.dbd.S)--NH--.
Claims19
A polymer comprising
- a fullerene core;
- and
- a plurality of prepolymer units;
- wherein each of said prepolymer units is linked to a carbon atom of said core by a moiety M.sup.1 in the sequence of F--M.sup.1 --P, wherein F represents said fullerene core, P represents one of said prepolymer units, and M.sup.1 is independently selected from the group consisting of --O--(C.dbd.O)--NH--, --NH--(C.dbd.O)--NH--, --O--(C.dbd.S)--NH--, and --NH--(C.dbd.S)--NH--;
- a carbon atom of said core being bonded to the left-terminal oxygen or nitrogen atom of M.sup.1 and the right-terminal nitrogen atom of M.sup.1 being bonded to a carbon atom of each of said prepolymer units.
