通过Suzuki偶联反应合成了一种异靛蓝和三苯胺(TPA)基小分子。通过H-1 NMR、C-13 NMR和MS对所得分子进行了表征。所得分子在固体薄膜中吸收400至743 nm的光。根据吸收起始和循环伏安法计算所得分子的带隙分别约为1.67 eV和1.60 eV。利用所得小分子与[6,6]-苯基-C-61丁酸甲酯(PCBM)的共混物作为活性层，采用旋涂法制备了光伏电池。太阳能电池的开路电压（V-oc）为1.0V，最大功率转换效率为0.61%。这种高开路电压是溶液处理小分子有机太阳能电池文献中最高的。 (c) 2013 Elsevier B.V. 保留所有权利。
One isoindigo and triphenylamine (TPA) based small molecule was synthesized by Suzuki coupling reaction. The obtained molecule was characterized by H-1 NMR C-13 NMR and MS. The obtained molecule absorbs light from 400 to 743 nm in thin solid film. The band-gaps of the resulting molecule calculated from the absorption onset and cyclic voltammetry are respectively around 1.67 eV and 1.60 eV. Photovoltaic cell by using the blend of the obtained small molecule and [6,6]-phenyl-C-61 butyric acid methyl ester (PCBM) as an active layer was fabricated by spin-coating method. The solar cells show open-circuit voltage (V-oc) of 1.0V with maximum power conversion efficiency 0.61%. This high open-circuit voltage is among the highest in literatures for solution processed small molecule organic solar cells. (c) 2013 Elsevier B.V. All rights reserved.
