  在棒段中心具有侧向甲基和乙基的线圈-棒-线圈分子的合成和自组装†

  摘要：

  棒-螺旋分子由柔性和刚性嵌段组成，具有很强的自组装能力，可以以大块状态自组装成各种有序的纳米结构。在本文中，我们报告了线圈-棒-线圈低聚物的自组装行为的合成和表征。这些新材料由5个联苯醚键连接在一起的五个联苯组成一个杆段，并在杆组成单元和聚环氧乙烷的中心并入了侧向的甲基或乙基（聚醚）的聚合度（DP）为7、12和17个线圈段。通过差示扫描量热法（DSC）和X射线散射（XRD）在本体状态下对这些分子进行结构研究，发现杆段中间的侧链，甲基和乙基极大地影响了分子的自组装行为。液晶相。含有侧甲基的分子基于聚醚 盘绕链（DP为12和17）在液晶相中自组织为六边形穿孔层（HPL）结构，而带有侧向乙基的分子基于 聚醚线圈链（DP为7）自组装为二维矩形柱状液晶结构。随着含乙基分子的线圈长度的进一步增加，分子在结晶相中自组织成一维层状结构。

  Aprocess for producing p,p'-biphenol which comprises heating a 4,4'-bis(substituted phenol) at elevated temperatures below the decomposition temperature of p,p'-biphenol in the absence of a catalyst under an inert non-reactive atmosphere for the length of time sufficient to obtain a reaction product containing a substantial amount of p,p'-biphenol while removing the olefin by-product formed and then recovering the p,p'-biphenol product. The 4,4'-bis (substituted phenol) is made by oxidative coupling of a phenol having the formula wherein R, and R2 may be the same or different and is a member selected from the group consisting of alkyl radicals containing from 2 to 10 carbon atoms, aralkyl radicals containing from 8 to 10 carbon atoms and having a β alkyl carbon - hydrogen group, and cyclic alkyl radicals having a /3 alkyl carbon - hydrogen group with oxygen or an oxygen containing gas in the presence of a catalytic quantity of a catalyst selected from the group consisting of alkali metal hydroxides, alkali metal salts of a weak acid, alkaline earth metal hydroxides, alkaline earth metal salts of a weak acid, amine bases, and mixtures of the same at an elevated temperature forthe time necessary to react up to a stoichiometric amount of oxygen with said phenol to form a reaction product containing a substantial amount of 4,4'-bis(2,6,-disubstitutedphenol).
