以正丁基吡啶四氟硼酸盐[bupy] BF 4和1-正丁基-3-甲基咪唑四氟硼酸盐[bmim] BF 4为溶剂，三乙胺为助催化剂，Rh（I）催化苯乙炔聚合，获得了高产率的聚苯乙炔。使用的络合物是（二烯）Rh（acac）和[（二烯）RhCl]2[二烯：1，5-环辛二烯或降冰片二烯]。在两种离子液体中的（nbd）Rh（acac）络合物可以再循环而活性没有显著损失。通过GPC测得分子量在55，000和200，000 Da之间。
The ionic liquids n-butylpyridinium tetrafluoroborate [bupy]BF4and 1-n-butyl-3-methylimidazolium tetrafluoroborate [bmim]BF4have been used as solvents for the Rh(I) catalyzed phenylacetylene polymerization in the presence of triethylamine as co-catalyst, obtaining high yields of poly(phenylacetylene). The complexes used are (diene)Rh(acac) and [(diene)RhCl]2[diene: 1,5-cyclooctadiene or norbornadiene]. The (nbd)Rh(acac) complex in both ionic liquids can be recycled without significant loss in activity. Molecular weights in the range between 55,000 and 200,000Da have been obtained by GPC.
