Organic light-emitting diodes (OLEDs) have attracted great attention because of their potential applications in full-color displays and solid-state lights. In the continual effort to search for ideal materials for OLEDs, small molecules with bipolar transporting character are extremely attractive as they offer the possibility to achieve efficient and stable OLEDs even in a simple single-layer device. In this Research News, we review the two design strategies of bipolar materials for OLEDs: molecules with or without donor-acceptor structures. The correlation between the experimental results and theoretical calculations of some of the materials is also discussed.
有机发光二极管（OLEDs）因其在全色显示器和固态照明中的潜在应用而受到极大关注。在不断寻找理想的 OLEDs 材料的过程中，具有双极传输特性的小分子因其有可能在简单的单层器件中实现高效和稳定的 OLEDs 而极具吸引力。在这篇研究新闻中，我们回顾了用于 OLEDs 的双极材料的两种设计策略：具有给体-受体结构或没有给体-受体结构的分子。我们还讨论了一些材料的实验结果和理论计算之间的相关性。
