一种新型供体-受体（D-A）共聚物（PIPY-DTBTA），含有6,12-二氢-二茚并[1,2-b；合成并表征了 1',2'-e] 吡嗪供体和苯并三唑受体，用于有机场效应晶体管 (OFET)、聚合物太阳能电池 (PSC) 和聚合物发光二极管 (PLED) 中的多功能应用。该聚合物具有高分子量、优异的成膜能力、深的HOMO能级和良好的溶液加工性能。基于该聚合物的溶液加工薄膜 OFET 显示出良好的 p 型特性，空穴迁移率高达 0.0521 cm(2) V (1) s (1)。包含该聚合物和 PC61BM 的体异质结 PSC 的功率转换效率 (PCE) 为 0.77%。基于 PIPY-DTBTA 的单层 PLED 在开启电压为 6 V 时发出黄红色光，最大亮度为 385 cd m (2)。 (C) 2012 Elsevier B.V. 保留所有权利。
A new donor-acceptor (D-A) copolymer (PIPY-DTBTA) containing 6,12-dihydro-diindeno[1,2-b; 1',2'-e] pyrazine donor and benzotriazole acceptor was synthesized and characterized for multifunctional applications in organic field-effect transistors (OFETs), polymer solar cells (PSCs) and polymer light-emitting diodes (PLEDs). The polymer exhibits high molecular weights, excellent film-forming ability, a deep HOMO energy level, and good solution processability. Solution-processed thin film OFETs based on this polymer revealed good p-type characteristic with a high hole mobility up to 0.0521 cm(2) V (1) s (1). Bulk-heterojunction PSCs comprising this polymer and PC61BM gave a power conversion efficiency (PCE) of 0.77%. The single-layer PLEDs based on PIPY-DTBTA emitted a yellow-red light with a maximum brightness of 385 cd m (2) at the turn-on voltage of 6 V. (C) 2012 Elsevier B.V. All rights reserved.
