摘要
以对溴苯酚为原料,经四步反应合成一种取代苯乙炔单体4-乙炔基-(2,6)二羟甲基-1-十二烷基酚醚。利用手性的铑催化剂引发聚合,得到高分子量的螺旋聚合物,通过GPC和CD对分子量和螺旋结构进行表征。最后通过光环化反应高效合成了环状三聚体,并通过1HNMR和GPC确认其化合物结构。
A monomer 4-ethinyl-2,6-bis（hydroxymethyl）-1-dodecyloxy benzene was synthesized by four-step reactions and by using bromophenol as raw materials. The monomer was polymerized by using the chiral rhodium catalyst system to get high molecular weight chiral polymer. Then the molecular weight and helical structure of the polymer were analyzed by GPC and CD. The cyclic trimer was synthesized by highly selective photocyclic aromatization reaction, structure of the compounds were confirmed by IHNMR and GPC.
