Abstract:
A multiply-substituted fullerene compound having the structure: ##STR40## wherein: Z.sub.1, Z.sub.2 and Z.sub.3 are absent or present, provided that at least one is present, and are independently selected from the group consisting of --NR.sub.1 --, --O--CR.sub.1 R.sub.2 --, --S--CR.sub.1 R.sub.2 --, --NR.sub.1 --CR.sub.2 R.sub.3 --, --R.sub.1 R.sub.2 C--NR.sub.3 --NR.sub.4 --, --R.sub.1 R.sub.2 C--NR.sub.3 --O--, --N.dbd.NR.sub.1 --, --N.dbd.N--NR.sub.1 --, --N.dbd.N--CR.sub.1 R.sub.2 --, --O--NR.sub.1 --O--, --R.sub.1 R.sub.2 C--O--CR.sub.3 R.sub.4 --, --R.sub.1 R.sub.2 C--O--NR.sub.3 --, --R.sub.1 C.dbd.N--O--, --R.sub.1 N--NR.sub.2 --NR.sub.3 --, --R.sub.1 N--NR.sub.2 --O--, --CR.sub.1 R.sub.2 --CR.sub.3 .dbd.CR.sub.4 --, --CR.sub.1 R.sub.2 --CR.sub.4 R.sub.4 --CR.sub.5 CR.sub.6 --CR.sub.7 R.sub.8 --, --CR.sub.1 R.sub.2 --CR.sub.3 .dbd.CR.sub.4 --CR.sub.5 R.sub.6 --, --CR.sub.1 .dbd.CR.sub.2 --CR.sub.3 .dbd.CR.sub.4 -- and --CR.sub.1 R.sub.2 --CR.sub.3 .dbd.C.dbd.CR.sub.4 -- such that Z.sub.1, Z.sub.2 and Z.sub.3 are each attached to the carbon skeleton of the fullerene structure by two single bonds selected from the group consisting of a carbon-carbon bond, a carbon-oxygen bond, a carbon-sulfur bond and a carbon-nitrogen bond, the unsatisfied valences of each Z moiety being the location of those bonds;R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are the same or different and are selected from the group consisting of hydrogen, oxygen, lower alkyl, higher alkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, carboxylic acids, carboxylic esters, alkylthio, thioalkyl, aryl, aryloxy, aralkyl, primary amine, secondary amine, amino acid side chains, and heterocycles, such that C together with any two R groups bonded thereto forms an oxo or thioxo group, hydrocarbon ring or heterocycle;Y.sub.1 and Y.sub.2 are absent or present, provided that at least one is present, and are selected from the group consisting of hydrogen, lower alkyl, higher alkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, alkylthio, thioalkyl, aryl, aryloxy, arylkyl, primary amine, secondary amine, amino acid side chains, and heterocycles;20<n<240;(k.sub.1 +k.sub.2) is 1 to n; and(m.sub.1 +m.sub.2 +m.sub.3) is 1 to n/2, with the limitation that 2(m.sub.1 +m.sub.2 +m.sub.3)+(k.sub.1 +k.sub.2)<n; or a salt or addition compound thereof.
