Significant progress has been achieved in the preparation of semiconducting polymers over the past two decades, and successful commercial devices based on them are slowly beginning to enter the market. However, most of the conjugated polymers are hole transporting, or p-type, semiconductors that have seen a dramatic rise in performance over the last decade. Much less attention has been devoted to electron transporting, or n-type, materials that have lagged behind their p-type counterparts. Organic electron transporting materials are essential for the fabrication of organic p-n junctions, organic photovoltaic cells (OPVs), n-channel organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs) and complementary logic circuits. In this critical review we focus upon recent developments in several classes of electron transporting semiconducting polymers used in OLEDs, OFETs and OPVs, and survey and analyze what is currently known concerning electron transporting semiconductor architecture, electronic structure, and device performance relationships (87 references).
在过去的二十年中,半导体聚合物的制备取得了重大进展,基于它们的成功商业设备也慢慢开始进入市场。然而,大多数共轭聚合物都是空穴传输,或者说是 p 型半导体,在过去十年中,其性能有了显著提高。而电子传输,或者说是 n 型材料,却很少受到关注,它们的发展落后于 p 型材料。有机电子传输材料对于制造有机 p-n 结、有机光伏电池 (OPV)、n 沟道有机场效应晶体管 (OFET)、有机发光二极管 (OLED) 和互补逻辑电路至关重要。在这篇重要的综述中,我们集中讨论了用于 OLED、OFET 和 OPV 的几类电子传输半导体聚合物的最新进展,并调查和分析了目前已知的关于电子传输半导体结构、电子结构和器件性能关系的情况(87 篇参考文献)。
