  have a great effect on the electronic absorption and energy levels of the conjugated compounds, particularly the effect of terminal groups. The terminal withdrawing and donating groups of thiophenoazomethines led to the formation of an electronic push–pull, push–push and pull–pull system, which can perturb the electronic transitions between the ground and excited states. The flexible chain substituents

  通过容易获得的胺与各种醛的反应，实现了通往对称和不对称噻吩并亚甲基的合成路线。对该方法得到的一系列噻吩并亚甲基的研究表明，末端基团和共轭程度对共轭化合物的电子吸收和能级有很大影响，尤其是末端基团的影响。噻吩并亚甲基的末端撤离和供体基团导致形成电子推拉、推拉和拉拉系统，这可以扰乱基态和激发态之间的电子跃迁。噻吩单元上的柔性链取代基提高了其溶解度，也导致了红移吸收，但对能级的影响有限。

  The present invention relates to conjugated oligomers and polymers comprising aromatic thiophene cores. The conjugated materials are obtained by simple and efficient condensation of an aryl diamine and an aryl dialdehyde or a bifunctional aryl moiety comprising both an aldehyde and an amine. Condensation of the complementary moieties at temperatures ranging from ambient to refluxing temperatures in various solvents resulted in conjugated oligomers and polymers that can subsequently be cast into thin films. Oligomerization and polymerization can be done under mild conditions with removal of the resulting water bi-product responsible for shifting the equilibrium in favour of the conjugated products. The resulting conjugated compounds can be made conducting with dopants affording electrically conducting materials of either p-type or n-type conductors depending on the dopant selected.

  本发明涉及含有芳香硫吡咯核的共轭寡聚物和聚合物。这些共轭材料是通过芳香族二胺和芳香族二醛或具有同时含有醛和胺的双官能团芳香族基团的简单而有效的缩合反应获得的。在各种溶剂中，在从常温到沸点温度的温度范围内缩合互补的官能团，得到了可以随后铸造成薄膜的共轭寡聚物和聚合物。在温和的条件下进行寡聚和聚合，去除产生的水副产物，有利于使平衡向共轭产物方向移动。所得的共轭化合物可以通过掺杂制成导电材料，根据所选择的掺杂剂，可以得到p型或n型导体的电导材料。
