hydrocarbon analogues, these perfluoromacrocycles are very stable materials which should have a number of applications. The crystal structures of perfluoro-18-crown-6 and of a perfluorodicyclohexano-18-crown-6 isomer are reported. Gas-phase studies with several perfluoro crown ethers and with the perfluorocryptand [222] have shown that such macrocycles tenaciously bind O[sub 2][sup [minus]] and F[sup [minus]]
全氟大环 perfluoro-18-crown-6, perfluoro-12-crown-4, perfluoro-15-crown-5, perfluoro-cyclohexano-15-crown-5, perfluorodicyclohexano-18-crown-6, perfluorodicyclohexano-24-crown -8, 和 perfluoro-4,7,13,16,21,24-hexaoxa-1, 10-diazabicyclo[8,8,8] hexacosane(perfluorocryptand [222]) 已经通过精心控制的元素氟化制备。尽管它们的碱比它们的烃类似物弱得多,但这些全氟大环是非常稳定的材料,应该有许多应用。报告了全氟-18-冠-6 和全氟二环己基-18-冠-6 异构体的晶体结构。使用几种全氟冠醚和全氟穴状配体 [222] 的气相研究表明,此类大环顽固地结合
