Bidipyrrin Au-III Complex as a Helical Charged & pi;-Electronic System

A series of ion pairs based on abidipyrrin-Au-III complexthat acts as a stable helical & pi;-electronic cation have beenprepared via ion-pair metathesis. The helical cation, which exhibitsNIR absorption and phosphorescence emission, formed solid-state ion-pairingassemblies, whose assembling modes depended on the properties of coexistingcounteranions.

Automated summary

A series of stable helical π-electronic cations based on ion pairs of abidipyrrin-Au-III complex have been prepared via ion-pair metathesis. The helical cation exhibits NIR absorption and phosphorescence emission, and forms solid-state ion-pairing assemblies with assembling modes depending on the properties of coexisting counteranions.
