通过将2,7‐二溴‐10,11‐二（2‐己基癸氧基）二噻吩[2,3‐d:2 ‘,3 ’‐d ']萘[2,1‐b:3,4‐b ']二噻吩（NDT‐Br）与三种不同的单元：2,5‐二（三甲基锡基）噻吩，2,5‐二（三甲基锡基）噻吩[3,2‐b]噻吩和反式- 1,2‐二（三丁基锡基）乙烯共聚，制备了三种新型介质带隙（MBG）共轭聚合物（CPs）（分别命名为P1， P2和P3）。研究了聚合物的热学、光学和电化学性能。所有聚合物都具有良好的热稳定性和中等带隙（~ 1.9 eV）。组装了基于P1/P2/P3和[6,6]苯基- C61丁酸甲酯（PC61BM）共混物的原型体异质结光伏电池，并评估了光伏性能。在100mw cm−2照度（AM1.5）下，功率转换效率（pce）为1.61% ~ 2.43%。©2016 Wiley期刊公司j:。变异较大。Sci.2016、133、43288。
Three novel medium band gap (MBG) conjugated polymers (CPs) (named as P1, P2, and P3, respectively) were developed by copolymerizing 2,7‐dibromo‐10,11‐di(2‐hexyldecyloxy)dithieno[2,3‐d:2′,3′‐d′]naphtho[2,1‐b:3,4‐b′]dithiophene (NDT‐Br) with three different units: 2,5‐bis(tributylstannyl)thiophene, 2,5‐bis(trimethylstannyl)thieno[3,2‐b]thiophene andtrans−1,2‐bis(tributylstannyl)ethene, respectively. The thermal, optical, and electrochemical properties of the polymers were investigated. All of the polymers have good thermal stability and medium band gap (∼ 1.9 eV). Prototype bulk heterojunction photovoltaic cells based on the blend P1/P2/P3 and [6, 6] phenyl‐C61 butyric acid methyl ester (PC61BM) were assembled and the photovoltaic properties were assessed. Power conversion efficiencies (PCEs) of 1.61% ∼ 2.43% have been obtained under 100 mW cm−2illumination (AM1.5). © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2016,133, 43288.
