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]]
Synthesis of perfluoropoly(ethylene glycol) ethers: CF<sub>3</sub>–[O–CF<sub>2</sub>–CF<sub>2</sub>]<sub>n</sub>–O–R<sub>f</sub>(R<sub>f</sub>= CF<sub>3</sub>or C<sub>2</sub>F<sub>5</sub>; n= 1–5)

A new synthetic method for the preparation of high molecular weight fluorocarbon ethers has been developed; polyethylene oxide was caused to react with elemental fluorine under conditions carefully regulated to fragment and perfluorinate the polyether system and yield a number of new fluorocarbon ethers.
