摘要本研究借鉴合成冠醚的 Willianmson 反应, 通过缓慢滴加二******合成了重要中间体乙氧基醚链接的苯并菲二
聚体, 且避免了 2,3-二羟基四戊烷氧基苯并菲自身成环反应所导致单一冠醚苯并菲的生成. 进一步以该中间体为原料,
通过缩合反应, 最终得到了冠醚桥接苯并菲二聚体, 并用 1H NMR, 13C NMR 和 MALDI-TOF 质谱对产物的结构和纯度
进行了表征.

Abstract According to Willianmson reaction for the synthesis of crown ether ring, a very important inter-
mediate, alkoxy-chain linked two triphenylene moieties was synthesized essfully through a slow addi-
tion of bis(2-chloroethyl) ether to avoid the production of crown ether ring on single triphenylene from
2,3-dihydroxy-tetrakis(pentyloxy)-triphenylene. Furthermore, a crown ether bridged triphenylene dimer was
finally achieved via the condensation reaction of bis(2-chloroethyl) ether with the intermediate. The final

product was characterized by H NMR, C NMR and MALDI-TOF spectra.
