title: Heteroaryl-substituted C3-bridged oligopyrroles: potential building subunits of anion-responsive pi-conjugated oligomers.
abstract: Acyclic anion receptors (BF 2 complexes of dipyrrolyldiketones) with heteroaryl moieties synthesized by using cross-coupling reactions have unique electronic states, as observed in UV/vis absorption spectra. Among heteroaryl-substituted derivatives, a pyrrolyl-substituted receptor exhibits an extremely high affinity for anions in solution.
