Complex impedance data demonstrate that addition of 2.2.2-cryptand increases the conductivity of NaSO3CH3 in amorphous poly(ethylene oxide) (aPEO) but decreases that of NaSO3CF3 in aPEO. Vibrational spectroscopic and X-ray diffraction measurements indicate that the influence of 2.2.2-cryptand is to dissolve crystallites of NaSO3CH3 into the polymer phase. The decrease in conductivity for NaSO3CF3-aPEO upon addition of 2.2.2-cryptand correlates with the precipitation of a crystalline phase, presumably [Na:2.2.2][SO3CF3].
