聚乙炔是最有希望的导电高分子,目前己在开发应用于制造塑料电池、太阳能电池等。合成聚乙炔膜的主要催化剂有Ti(OC_4H_9)_4-Al(C_2H_5)_3催化剂,稀土络合催化剂及Co(NO_3)_2-NaBH_4等。本文报道新开发的周期表中第22号元素钛至第28号元素Ni的笫四周期过渡金属——Ti,V,Cr,Mn,Fe,Co,Ni的膦酸酯盐与三烷基铝组成的新络合催化剂合成聚乙炔膜的特征。除镍外,这些催化剂都可以使乙炔在室温下聚合生成顺式含量50％以上、高结晶性、有金属光泽的银灰色聚乙炔膜。在实验范围内,各催化体系聚合活性次序如下:Fe>Ti,V>Cr>Mn>Co>Ni,并且表征了所制备的聚乙炔膜,这些新催化剂的开发为合成聚乙炔提供了方便和有利条件。
Polyacetylene is the most promising conductive polymer, has been developed in the manufacture of plastic batteries, solar cells and so on. The main catalysts for the synthesis of polyacetylene films are Ti (OC_4H_9) _4-Al (C_2H_5) _3 catalysts, rare earth complex catalysts and Co (NO_3) _2-NaBH_4. This article reports the new development of the periodic table in the 22nd element of titanium to the 28th element Ni fourth cycle transition metal - Ti, V, Cr, Mn, Fe, Co, Ni phosphonate salt and trialkylaluminum The composition of the new complex catalyst for the synthesis of polyacetylene film characteristics. In addition to nickel, these catalysts allow acetylene to polymerize at room temperature to produce a silver gray polyacetylene film having a cis content of more than 50%, high crystallinity and a metallic luster. Within the experimental range, the order of the polymerization activity of each catalytic system is as follows: Fe> Ti, V> Cr> Mn> Co> Ni, and the polyacetylene films prepared were characterized. The development of these new catalysts provided convenient and Favorable conditions
