We have prepared rigidly linear π-conjugated polymers by organometallic polycondensation using nickel and palladium complexes. These π-conjugated polymers were electrically conductive after doping, and showed electrochemically active and luminescent properties. The synthesized polymers contain poly(arylene)s and poly(aryleneethynylene)s composed of pyrimidopyridine, pyridopyradine, 3,4-ethylenedioxythiophene, and pyrimidine. We have revealed their photoluminescent, electrically conducting, and electrochemical responses, as well as their intermolecular interaction and packing structure in the solid originated from the rigidly linear structure. Spectroscopy and powder X-ray diffraction methods gave fundamental information about the polymers.The π-conjugated polymers are usually photoluminescent and sometimes show electroluminescence. The polymers give a high viscosity due to their rigidly linear structure and exhibit a strong dichroism in stretched films. In the course of the polymerization, formation of intermediate organo-nickel and-palladium complexes is strongly suggested. We prepared model compounds for the intermediates and analyzed their molecular structure.The obtained π-conjugated polymers take p2gg or face-to-face aggregated packing structure in the solid due to the intermolecular interaction, and the packing mode influenced efficiency of the luminescence. The ease of oxidation and reduction of the polymers reflect the basic electronic properties of the repeating units.

我们已经通过使用镍和钯络合物来制备有机多浓度刚性线性π共轭聚合物。这些π偶联的聚合物在掺杂后是电导性的，并显示出电化学活性和发光特性。合成的聚合物含有聚（芳基）S和聚（芳基乙烯基）S，由嘧啶吡啶，吡啶吡啶，3,4-乙基二羟基噻吩和嘧啶组成。我们已经揭示了它们的光致发，电导和电化学响应，以及它们的固体中分子间相互作用和填料结构，起源于刚性线性结构。光谱和粉末X射线衍射方法提供了有关聚合物的基本信息。 π偶联的聚合物通常是光致发光的，有时会显示电致发光。聚合物由于其刚性的线性结构而产生的粘度很高，并在拉伸膜中表现出强烈的二分法。在聚合过程中，强烈建议形成中间有机鸡和钯络合物。我们为中间体制备了模型化合物，并分析了它们的分子结构。获得的π共偶联聚合物在固体中服用P2GG或面对面的聚合堆积结构，这是由于分子间相互作用，填料模式影响了发光效率。聚合物的氧化和还原的易感性反映了重复单元的基本电子特性。
