Emission: Highly Fluorescent and Color‐Tunable Exciplex Emission from Poly(N‐vinylcarbazole) Film Containing Nanostructured Supramolecular Acceptors (Adv. Funct. Mater. 19/2014)

S. Y. Park and co-workers demonstrate a novel and effective method to achieve highly efficient and color-tuned (sky blue, green, and orange) exciplex emissions originating from the nanoscale interface between a polymeric donor—poly(N-vinylcarbazole) (PVK)—and highly fluorescent nanostructured acceptors. An unprecedented approach to obtain a white-emitting PVK film consisting of multiple exciplex emissions is also presented. Exciplex-to-exciton emission color switching due to the size evolution of the nanostructured acceptors is demonstrated and photophysically interpreted.
