The first phosphorus-containing crown ethers with regularly alternating arylene and phosphorus acid residues have been obtained. Structural peculiarities and some chemical properties of these compounds have been studied. Rhodium complexes of new phosphorus-containing macrocycles have been prepared.
## Abstract **Summary:** The synthesis and polymerization of novel 18βcrownβ6 and 24βcrownβ8 bis aryl trifluorovinyl ethers is described. Thermally induced polymerization yields linear crown ether fluoropolymers with hexafluorocyclobutyl linkages. The polymers exhibit __T__~g~'s above 120βΒ°C and sh
