新型杯4冠醚衍生物聚合单体的合成

摘要

从对叔丁基杯[4]芳烃出发,对其下沿的酚羟基进行修饰,先后在1,3-和2-酚羟基位点引入冠醚环和乙基；最后在NaH/THF中与3-溴丙烯酸丙酯反应制得聚合单体——新型杯[4]冠醚衍生物,其结构经1H NMR和MS表征.%A novel vinylic calix[4]crown monomer was synthesized fromp-t-butylcalix[4]arene by introducing branched crown ether and ethyl at 1,3- and 2-posions of phenolic hydroxyl groups, then by the reaction of 5,7,11,23-tetra-t-butyl-25-hydroxy-27-ethyoxycalix[4]crown-5 with 3-bromoprop-yl acrylate in NaH/THF solution. The structure was characterized by 1H NMR and MS.
