Abstract
Nanobelts are a rapidly developing family of macrocycles with appealing features. However, their host-guest chemistry is currently limited to the recognition of fullerenes via π–π interactions. Herein, we report two heteroatom-bridged [8]cyclophenoxathiin nanobelts ([8]CP-Me and [8]CP) encapsulate corannulene (Cora) to form bowl-in-bowl supramolecular structures stabilized mainly through CH–π interactions in solid-state. The convex surface of corannulene is oriented towards the cavity due to geometry complementarity. The complex Cora⊂[8]CP exhibits a unique 2:2 capsule-like structure in crystal packing, in which corannulene adopts a concave-to-concave assembling fashion. This work enriches the molecular recognition of nanobelts and demonstrates that CH–π interactions can act as the main driving force for nanobelts host-guest complexes.
