Two new dibenzocrown ethers and molecular clips were synthesized. The influence of substituents on the terminal aromatic fragments of the clips on the paraquat-complex stability constants were studied. The “pseudocryptand” type complex of fluorine-substituted clip 1 with paraquat hexafluorophosphate was found in the crystalline state.
