Organic electroluminescent devices working under alternating current electricity have drawn both scientific and technological attention due to their unique light-emitting principles of carrier generation and recombination and have great potential for applications in displays and sensors. In this manuscript, we report high-performance full-color AC EL devices with non-radiating polymers solution-blended in fluorescent polymer emissive layers. Systematic investigation revealed bi-functional roles of PS not only as a diluting agent capable of suppressing non-radiative interchain fluorescent quenching but also as an electron capturer. Furthermore, our blended emission film consisting of 83 vol% PS is robust with excellent surface adhesion as well as uniformity not only resulted in large area cell operation but also allowed for a solution-based pattern-mask process with detachable Scotch tape, giving rise to well-defined R, G and B cells individually addressable in a single device platform. |
