Luminescent properties of dicyanoaurate(I) aggregates based on electrostatic assembly along poly(allylamine hydrochloride)

Poly(allylamine hydrochloride) (PAA) bearing positively charged side chains along the polymer chain was demonstrated to serve as a polymeric spatially aligned scaffold for aggregation and self-association of negatively charged [Au(CN)2]− through the electrostatic and aurophilic bonding interactions to afford the luminescent [Au(CN)2]− aggregates.
