Viologen–Cycloparaphenylene Hybrids: Luminescent Molecular Nanocarbons for Anion Binding and Specific Vapor Sorption†

Two viologen-like macrocyclic receptors, [1]2+ and [2]2+, merging a bent oligophenylene loop with a (para-xylylene)bispyridinium moiety were designed and synthesized. Both dications were derived from the same precursor: the more...
