Organic light-emitting diodes (OLEDs) have great potential applications in display and solid-state lighting. Stability, cost and high operational efficiency are key issues governing the future commercial application of OLEDs. In this context, searching for multifunctional emitting materials with acceptable light-emitting and charge-transporting characteristics has gained increasing attention. For achieving high-performance and low-cost OLEDs, the suitable molecular design featured with different electronic and optical nature should be incorporated by combining the advantages of both functional units into the same molecules. This review highlights recent and current advances in developing bifunctional or multifunctional molecules, with the focus on structures, properties, and applications in OLEDs and organic laser.
