Viologen–cycloparaphenylene hybrids: luminescent molecular nanocarbons for anion binding and specific vapor sorption

Abstract

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...
