六周六苯并冠烯(HBC)衍生物具有许多有趣的性质，从液晶性到空穴传输，再到可变的发射行为，但受到可聚合取代基的不溶性和普遍可获得性的困扰。首次合成了三氟乙烯基醚取代的六苯并冠烯，并将其聚合为全氟环丁基(PFCB)聚合物和共聚物。与碳氢醚不同，氟乙烯基醚在HBC氧化条件下是稳定的。PFCB聚合物中的离散HBC单元提供了潜在的可加工HBC光学材料。
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.
