All-Hydrocarbon Inclusion Complexes of Carbon Nanorings: Cyclic [6]- and [8]Paraphenyleneacetylenes

Ringing the changes: The belt‐shaped π‐conjugated [6]‐ and [8]paraphenyleneacetylenes exhibit nanosized cavities (see picture), and act as host molecules in crystalline inclusion complexes with hexamethylbenzene and toluene, respectively. The concave side of the cavities appears to possess a negativ...

Zusammenfassung:Ringing the changes: The belt‐shaped π‐conjugated [6]‐ and [8]paraphenyleneacetylenes exhibit nanosized cavities (see picture), and act as host molecules in crystalline inclusion complexes with hexamethylbenzene and toluene, respectively. The concave side of the cavities appears to possess a negative electronic potential.
