通过Suzuki或Stille偶联反应，以较高的产率合成了3种主链上含有3，4-二（4-己基噻吩-2-基）-3-环丁烯-1，2-二酮单元的新型共轭聚合物。它们的结构经FT-IR、1HNMR和13 CNMR确证。所有这些共聚物在紫外-可见光区都有较强的吸收带，其光学带隙为1.6- 2.0eV，表明它们对太阳光谱有较好的覆盖性。这些聚合物具有良好的热稳定性和在普通有机溶剂中的溶解性。此外，所有这些目标大分子具有高的电子亲和势，从循环伏安法测量确定的类似3.8 eV，这意味着它们是潜在的n型聚合物光伏材料。(C)2011年，黄燕。Elsevier B.

Three novel conjugated polymers bearing 3,4-bis(4-hexylthiophen-2-yl)-3-cyclobutene-1,2-dione unit in their main chain have been synthesized successfully in good yields through Suzuki or Stille coupling reaction. Their molecular structures have been confirmed by FT-IR, (1)H NMR and (13)C NMR. All these copolymers exhibit broad and strong absorption bands in UV-vis region, and their optical band gaps are calculated to be 1.6-2.0 eV, suggesting that they have good coverage with the solar spectrum. These polymers have good thermostability and solubility in common organic solvents. Moreover, all these objective macromolecules possess high electron affinity of similar to 3.8 eV determined from cyclic voltammetry measurement, implying that they are potential n-type polymeric photovoltaic materials.
