Dehalogenation polycondensation of corresponding dihalo compounds with zerovalent nickel complex gives soluble pi-conjugated polymers, poly (pyridine-2,5-diyl) (PPy) , poly (3-hexylthiophene-2,5-diyl) (PHTh) and poly (thiophene-2,5-diyl) having a crown ethereal subunit (PThCr) .Analytical, IR and NMR data agree with the structure of the polymers. PPy has good solubility in formic acid, whereas PHTh and PThCr are soluble in many common organic solvents such as CHCl_3 and THF.These polymers behave as an electrically conductive materials. PPy films reversibly change color from yellow to dark bule during poping and undoping process, whereas PHTh films change from orange red to bule. The Al/PThCr/ITOglass electric junction shown an electroluminescent property. The electric junction starts emitting light at an applied voltage of about 6 V.The peak position of the light emission is about 470nm. As described above, PPY,PHTh and PThCr are electrochemically active and usable in making devices such as electrochromic and electroluminescence device.

相应的二卤代化合物与零价镍络合物的脱卤缩聚得到可溶性π共轭聚合物，聚(吡啶-2,5-二基)(PPy)、聚(3-己基噻吩-2,5-二基)(PHTh)和聚(噻吩) -2,5-二基）具有冠醚亚基（PThCr）。分析、红外和核磁共振数据与结构一致聚合物。 PPy 在甲酸中具有良好的溶解度，而 PHTh 和 PThCr 可溶于许多常见的有机溶剂，如 CHCl_3 和 THF。这些聚合物表现为导电材料。在爆裂和去掺杂过程中，PPy 薄膜的颜色可逆地从黄色变为深蓝色，而 PHTh 薄膜则从橙红色变为蓝色。 Al/PThCr/ITO玻璃电结表现出电致发光特性。电结在施加约6V的电压时开始发光。发光的峰值位置约为470nm。如上所述，PPY、PHTh和PThCr具有电化学活性并且可用于制造器件例如电致变色和电致发光器件。
