合成了基于两种不同角型萘并二呋喃（NDF）的新型聚合物。研究了该聚合物的光学、电化学和光伏性能。聚合物PIDNDF 1在稀溶液和薄膜中的紫外-可见吸收光谱均比聚合物PIDNDF 2发生红移。PIDNDF 1和PIDNDF 2的HOMO能级相似，为-5.40eV。这两种聚合物的LUMO能级略有差异。基于PIDNDF 1的太阳能电池器件的最大功率转换效率（PCE）为1.83%，这是基于PIDNDF 2的器件的两倍多。不同的NDF重复单元的形状和聚合物主链的几何形状导致了器件性能的差异。(C)2013爱思唯尔有限公司版权所有。
New polymers based on two different angular-shaped naphthodifurans (NDFs) have been synthesized. The optical, electrochemical and photovoltaic properties of the new polymers were investigated. The UV-vis absorption spectra of polymer PIDNDF1 recorded in dilute solution and as thin-film were both red-shifted compared with those of polymer PIDNDF2. the HOMO energy levels of PIDNDF1, and PIDNDF2 were similar at -5.40 eV. There was slight difference in the LUMO energy levels of these two polymers. The maximum power conversion efficiency (PCE) of PIDNDF1, based solar cell devices was 1.83%, which was more than twice that of PIDNDF2 based device. The difference on the device performance resulted from the shapes of NDF repeating units and backbone geometries of polymers. (C) 2013 Elsevier B.V. All rights reserved.
