Title: Solution-processedexciplexfor highly efficient organic light-emitting devices
Abstract: 
Simplified solution-processed organic light-emitting devices composed of exciplex-based co-host and iridium complex-based red emitters were demonstrated. To balance hole and electron in the emissive zone, a hole transporting material featuring preferable hole mobility and abipolar host were blended. Consequently, due to the charge transfer process, exciplex emission was observed in the mixed co-host which led to superior charge balance in solution-processed emitting layers. Moreover, the higher singlet yield generated in the exciplex-based co-host guarantees better energy transfer to the emissive dopants, which further contributes to the superior electroluminescence performances.
