Abstract

We have developed a simple method to overcome the intrinsic defect of well-known poly[2-methoxy-5-(2′-ethylhexoxy)-p-phenylenevinylene] (MEH-PPV), i.e. rampant inter-chain interaction and imbalanced hole and electron fluxes, by blending with copolymer of polystyrene containing pendant aromatic 1,3,4-oxadiazole (PSOXD12). The addition of PSOXD12 reduces the inter-chain interaction and balances charge carrier transport simultaneously. Photoluminescence (PL), PL excitation and electroluminescence (EL) spectra of the blends reveal that the inter-chain interactions, such as aggregation and excimer/exciplex, are reduced markedly due to the presence of PSOXD12. Enhanced EL device performance has been achieved (16,261 cd/m², 4.79 cd/A) as a result of both reduced inter-chain interaction and balanced charge transport.
