在过去的二十年里，有机电子学领域由于其低成本、轻量化、机械灵活性、化学设计和合成的多功能性以及易于加工等优点而得到了巨大的发展。有机发光二极管（oled）、光电器件（opv）和场效应晶体管（ofet）等器件的性能和寿命严重依赖于活性材料及其界面的特性。界面性能可以控制，从简单的润湿性或不同材料之间的粘附性到材料的电子结构的直接修改。在这篇专题文章中，重点介绍了利用表面活性剂修饰阴极、空穴传输缓冲层和自组装单层（SAM）修饰阳极的策略。除了能够生产高效率的有机发光二极管外，传统和倒置聚合物太阳能电池中的界面控制也被证明可以提高其效率和稳定性；源漏极半导体接口、介电半导体接口和超薄介电体的剪裁显示可以实现高性能的ofet。
The field of organic electronics has been developed vastly in the past two decades due to its promise for low cost, lightweight, mechanical flexibility, versatility of chemical design and synthesis, and ease of processing. The performance and lifetime of these devices, such as organic light-emitting diodes (OLEDs), photovoltaics (OPVs), and field-effect transistors (OFETs), are critically dependent on the properties of both active materials and their interfaces. Interfacial properties can be controlled ranging from simple wettability or adhesion between different materials to direct modifications of the electronic structure of the materials. In this Feature Article, the strategies of utilizing surfactant-modified cathodes, hole-transporting buffer layers, and self-assembled monolayer (SAM)-modified anodes are highlighted. In addition to enabling the production of high-efficiency OLEDs, control of interfaces in both conventional and inverted polymer solar cells is shown to enhance their efficiency and stability; and the tailoring of source drain electrode semiconductor interfaces, dielectric semiconductor interfaces, and ultrathin dielectrics is shown to allow for high-performance OFETs.
