Abstract

Hexa-peri-hexabenzocoronene (HBC) derivatives possess many interesting properties ranging from liquid crystallinity, to hole transport, to variable emission behavior, yet are plagued by insolubility and general accessibility of polymerizable substituents. The first synthesis of trifluorovinyl ether-substituted hexabenzocoronene and its polymerization to perfluorocyclobutyl (PFCB) polymers and copolymers is shown. Unlike hydrocarbon ethers, fluoro vinyl ethers are stable under HBC oxidation conditions. Discrete HBC units in PFCB polymers provide access to potentially processable HBC optical materials.

摘要

六苯并蔻（HBC）衍生物具有许多有趣的特性，从液晶性到空穴传输，再到可变的发光行为，但却受到溶解性差和可聚合取代基普遍难以引入的困扰。本文展示了三氟乙烯基醚取代的六苯并蔻的首次合成及其聚合成全氟环丁基（PFCB）聚合物和共聚物的过程。与烃基醚不同，氟代乙烯基醚在HBC氧化条件下是稳定的。PFCB聚合物中的离散HBC单元为潜在可加工的HBC光学材料提供了途径。
