Supramolecular Complexes of Conjugated Polyelectrolytes with Poly(ethylene oxide): Multifunctional Luminescent Semiconductors Exhibiting Electronic and Ionic Transport

Abstract

Cyclodextrin-threaded molecular wires form supramolecular complexes with polymers featuring ion-coordination properties. The supramolecular interactions reduce the tendency of the different components to phase separate boosting the photo- and electroluminescence (EL) efficiencies. The Figure shows the EL enhancement of poly(4,4′-diphenylene vinylene) (PDV) blended with polyethylene oxide (PEO) as a funcion of PEO concentration.
