C-60(C6H4Me)(4)Ph-4: a fully substituted derivative of the pentagon-fused C60CI8

摘要

The eight chlorines of C60CI8 with two pairs of fused pentagons are successfully substituted by sterically encumbering groups through the Friedel Crafts reaction to get C-60(C6H4Me)(4)ph(4), which provides a facile way for multiple modification of special fullerenes.
