自1987年Tang和Van Slyke首次报道高效双层有机发光二极管以来，基于真空沉积小分子的有机发光二极管（OLEDs）取得了重大进展。近年来，溶液处理的小分子oled也受到越来越多的研究关注，因为这种技术结合了小分子易于合成和聚合物等低成本溶液工艺的优点。溶液法制备的有机发光二极管的性能正逐渐赶上真空法制备的有机发光二极管。本专题文章将回顾用于实现高性能溶液处理oled的器件结构，溶液可加工小分子的发展，以及溶液法和真空沉积法制备的薄膜和器件的不同性质的比较。最后，对研究前景和存在的问题进行了讨论。
Organic light-emitting diodes (OLEDs) based on vacuum deposited small molecules have undergone significant progress since the first efficient double-layered OLEDs were reported in 1987 by Tang and Van Slyke. Recently, solution processed small molecular OLEDs are also drawing more and more research attention, as such a technology combines advantages of the facile synthesis of small molecules and the low-cost solution process like polymers. The performance of OLEDs made by solution process is gradually catching up with their vacuum deposited counterparts. This feature article will review the device structures adopted to achieve high performance solution processed OLEDs, the development of solution processable small molecules, and the comparisons of the different nature of the films and devices fabricated by solution-process or by vacuum deposition. Finally, the prospects and remaining problems will be discussed.
