Ribbon pattern: An isomer of C84(CF3)12 fullerene with the C84-C2(11) cage (see molecular structure determined by X-ray crystallography) demonstrates a new principle of hollow higher fullerene reactivity: For 1,4-additions of bulky groups that produce ribbons or loops of edge-sharing p-C6X2 hexagons, the “most reactive” double bonds remain intact.
