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.
