摘要:

經(jīng)過二十年的發(fā)展，真空蒸鍍和溶液法制備有機發(fā)光二極管的方法已經(jīng)取得了巨大的進步。相對于依賴真空蒸鍍成膜的有機小分子材料，可溶液法加工的小分子材料可降低器件制作成本、適合于制備制作大面積光電器件。同時，小分子材料可以較為明確的給出分子結(jié)構(gòu)與光電性能的構(gòu)效關系，因此濕法成膜制備的小分子OLEDs越來越受到人們關注。本文綜述了近期可濕法成膜的小分子材料設計理念，合成方法以及具體應用，討論了實現(xiàn)全濕法小分子OLEDs所面臨的挑戰(zhàn)以及解決的方法。

Abstract:

After 20 years of development, significant progress has been made in the development of organic light-emitting diodes (OLEDs), which can be fabricated via both vacuum deposition and solution processes. Recently, solution processed small molecular OLEDs are 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. In addition, small molecular materials can be more clearly gives the structure-activity relationships between the molecular structure and photoelectric properties. This review presents some recent developments in the design, synthesis and applications of organic solution-processable small materials, and discusses the challenge and solutions of achieving all-solution process small molecular OLEDs.
