摘　　要：以4-十二烷氧基-3,5-二甲酰基苯乙炔和十二烷基苯二胺为原料,首次设计并合成了一种含大体积π-共轭平面取代基的苯乙炔衍生物,并通过核磁共振确定了单体的化学结构。以铑络合物二[氯化(二环[2,2,1]庚-2,5-二烯)铑]为催化剂,手性胺(R)-苯乙基胺为共催化剂的手性催化体系中进行聚合,成功制备了含有大体积取代基的聚苯乙炔,该聚合物具有良好的成膜性,在CO2的气体分离方面具有潜在的应用价值。A novel polyphenylacetylene having two bulky π-conjugated substituents was designed and synthesized by using 4-dodecyloxy-3,5-diformylphenylacetylene and dodecyl-1,2-phenylenediamine as starting materials.The chemical structures of the products of each step were characterized by the proton NMR spectra. The new monomer was polymerized to give a polymer having two bulky π-conjugated substituents by using the rhodium complex（[Rh（nb d）Cl]2） as catalyst and the（R）-phenylethylamine（（R）-PEA） as cocatalyst. The resulting polymer showed good membr ane forming ability and will be able for separation of carbon dioxide as a polymer membrane.
