Claim:
1. A photoresist composition comprising at least one fullerene compound comprising the general formula: a wherein Z forms a ring structure with the C2x fullerene chosen from A, B, and C below: wherein x is at least 10, y is 1 -6, R 1 is a C 1 to C 30 branched or unbranched, substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl, heterocyclic, alkylheterocyclic substituent or a substituent which coordinates with a least one metal, and R 2 is a substituent which coordinates with at least one metal, and wherein R 3 , R 4 and R 5 is, each independently, a 1-6, R 1 is a C 1 to C 30 branched or unbranched, substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl, heterocyclic, alkylheterocyclic substituent or a substituent which coordinates with a least one metal, b. at least one solvent, c. at least one photoacid generator, and d. optionally, at least one of a component chosen from a crosslinker, an alkali soluble and polymer protected by an acid-labile group.
