Cocrystallization of Imide-Fused Corannulene Derivatives and C60 : Guest-Induced Conformational Switching and 1:1 Segregated Packing.

A pair of interconvertible stereoisomers of imide-fused corannulene derivatives was mixed with C60 , which resulted in cocrystallization into a 1:1 segregated packing motif through concave-convex π-π interactions. Only one conformation was observed in the cocrystal owing to guest-induced conformational switching. The 1D assemblies of the complex showed promising applications in organic electronics.
