两种新型交替π共轭共聚物聚[2，8-（6，6 ′，1,2，1,2 ′-四辛基-6，1,2-二氢茚并[1，2b]芴- alt-5（1-（2，6-二异丙基苯基）-2，5-二（2-噻吩基）吡咯）（P1）和聚[2，8-采用Suzuki偶联法合成了（6，6 ′，1,2，1,2 ′-四辛基-6，1,2-二氢茚并[1，2b]芴- alt-5-（1-（对辛基苯基）-2，5-二（2-噻吩基）吡咯）（P2），并对其光电性质进行了研究。所得聚合物P1和P2在各种常见有机溶剂中完全可溶，并且它们的重均分子量（Mw）分别为5.66 × 104（多分散性：1.97）和2.13× 104（多分散性：1.54）。采用ITO/PEDOT：PSS/聚合物：PC 70 BM（1：5）/TiOx/Al配置制造了体异质结（BHJ）太阳能电池。具有P1：PC 70 BM（1：5）的BHJ太阳能电池具有1.12%的功率转换效率（PCE）（Jsc= 3.39mA/cm 2，Voc= 0.67V，FF = 49.31%），使用AM 1.5G太阳模拟器在100 mW/cm 2光照下测量。我们制备了ITO/PEDOT：PSS/发光聚合物：聚乙二醇（PEG）/Ba/Al结构的聚合物发光二极管（PLED）。所制备的PLED的电致发光（EL）最大值从526 nm到556 nm变化，这取决于聚合物与PEG的比例。PLED的开启电压在3-8 V的范围内，取决于聚合物与PEG的比例，并且在12 V下的最大亮度和发光效率分别为2103 cd/m2和0.37 cd/A。© 2010 Wiley Periodicals，Inc.聚合物科学杂志A部分：聚合物化学48：3169-3177，2010年

Two novel alternating π-conjugated copolymers, poly[2,8-(6,6′,12,12′-tetraoctyl-6,12-dihydroindeno-[1,2b]fluorene- alt-5(1-(2,6-diisopropylphenyl)-2,5-di(2-thienyl)pyrrole) (P1) and poly[2,8-(6,6′,12,12′-tetraoctyl-6,12-dihydroindeno-[1,2b]fluorene- alt-5(1-(p-octylphenyl)-2,5-di(2-thienyl)pyrrole) (P2), were synthesized via the Suzuki coupling method and their optoelectronic properties were investigated. The resulting polymers P1 and P2 were completely soluble in various common organic solvents and their weight-average molecular weights (Mw) were 5.66 × 104 (polydispersity: 1.97) and 2.13× 104 (polydispersity: 1.54), respectively. Bulk heterojunction (BHJ) solar cells were fabricated in ITO/PEDOT:PSS/polymer:PC70BM(1:5)/TiOx/Al configurations. The BHJ solar cell with P1:PC70BM (1:5) has a power conversion efficiency (PCE) of 1.12% (Jsc= 3.39 mA/cm2, Voc= 0.67 V, FF = 49.31%), measured using AM 1.5 G solar simulator at 100 mW/cm2 light illumination. We fabricated polymer light-emitting diodes (PLEDs) in ITO/PEDOT:PSS/emitting polymer:polyethylene glycol (PEG)/Ba/Al configurations. The electroluminescence (EL) maxima of the fabricated PLEDs varied from 526 nm to 556 nm depending on the ratio of the polymer to PEG. The turn-on voltages of the PLEDs were in the range of 3–8 V depending on the ratio of the polymer to PEG, and the maximum brightness and luminance efficiency were 2103 cd/m2 and 0.37 cd/A at 12 V, respectively. © 2010 Wiley Periodicals, Inc.
