Corannulene and its penta-tert-butyl derivative co-crystallize 1 : 1 with pristine C60-fullerene

Abstract

The first X-ray structural determinations of pristine fullerene C(60), cocrystallized 1:1 with corannulene and with its pentaalkyl-substituted derivative, 1,3,5,7,9-penta-tert-butyl-corannulene, have now been achieved.

Self‐Assembly of Bowl‐Shaped Naphthalimide‐Annulated Corannulene

“…Bowl‐shaped molecules are widely applied in the field of supramolecular chemistry as hosts for fullerene molecules after Scott and coworkers first showed the assembly of C 60 with corannulene in the solid state and in solution due to the complementary intimate concave‐convex π ‐ π ‐interactions. By connecting two bowl‐shaped precursors with a rigid bridge, it was further possible to synthesize the “buckycatcher”, a molecular tweezer which is able to form a supramolecular 1 : 1 complex with C 60 through concave‐convex π ‐ π ‐interactions .…”

Programmed Hierarchical Hybrid Nanostructures from Fullerene‐Dendrons and Pyrene‐Dendrons

“…Additionally, tetrathiafulvalene calix[4]pyrroles‐based receptors for C 60 have been significantly studied by Sessler group . Although a large number of C 60 receptors have been reported to be applied to host–guest systems, studies to control the hierarchical nanostructures of C 60 resulting in the target properties are very limited …”

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

“…The interactions between pristine corannulene and C 60 in solution have been proven by fluorescence titration . Their interactions in the solid state were also confirmed by single‐crystal data, and strong concave–convex π–π interactions have been observed . To improve their interaction further, several elegant strategies have been developed, including periphery modification of corannulene with electron‐rich groups, the incorporation of multi‐corannulene pincers into one molecule,, and extension of the curved π surface .…”
