Abstract
The salts Na[CF3SO2N(CH2)(3)OCR3] and K[CF3SO2N(CH2)(3)OCH3] form amorphous complexes with cryptand and crown ether macrocycles, which exhibit substan tial ionic conductivity. The formation of an amorphous phase is thought to be favored by a mismatch between the cavity size of the macrocycle and the diameter of the cation. Complexes were examined by thermal, spectroscopic a nd conductivity methods to determine the role of the cation and the size mi smatch with complexing macrocycles on ionic glass formation.
