Abstract

The invention relates to an addition compound which is obtainable by reaction of a diamine of the formula I, ##STR1## where R.sup.1 is (C.sub.2 -C.sub.4)-alkylene or 1,2- or 1,3-cyclo-(C.sub.3 -C.sub.7)-alkylene and PA1 R.sup.2 and R.sup.3, which are identical or different, are (C.sub.1 -C.sub.3)-alkyl or hydrogen or PA1 R.sup.2 and R.sup.3 together are (C.sub.2 -C.sub.4)-alkylene, with fullerenes C.sub.60 and/or C.sub.70. The fullerene derivatives are useful as electrically conducting materials.
