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配合物进行脱卤缩聚反应，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）和含冠醚亚基的聚噻吩-2，5-二基（PThCr），分析、IR和NMR数据与聚合物的结构一致。PPy在甲酸中具有良好的溶解性，而PHTh和PThCr在CHCl_3和THF等常见有机溶剂中具有良好的溶解性，这些聚合物具有导电性。PPy膜在开膜和去开膜过程中颜色从黄色可逆地变为深蓝色，而PHTh膜从橙子红可逆地变为蓝色。Al/PThCr/ITO玻璃电结具有电致发光特性。电结在约6V的施加电压下开始发光。发光的峰值位置为约470 nm。如上所述，PPY、PHTh和PThCr是电化学活性的并且可用于制造诸如电致变色和电致发光器件的器件。
