One of the key features of organic optoelectronic and electronic devices resides in the multilayer architecture of the device stack. The performance of the latter strongly depends on the interface quality between organic layers or at the electrode heterojunction. Apart from interface thermodynamics governing adhesion and wetting, the electronic energy levels of the organic semiconductor are affected by the interface properties in a drastic way. This mini review gives a short overview on the possibilities to adjust frontier orbital energy levels using oriented electrical dipoles at the interfaces.
有机光电器件和电子器件的关键特性之一在于器件堆叠的多层结构。后者的性能在很大程度上取决于有机层之间或电极异质结处的界面质量。除了控制粘附和润湿的界面热力学外，有机半导体的电子能级也会受到界面性质的显著影响。本综述简要概述了利用界面处的定向电偶极来调整前沿轨道能级的可能性。
