Poly(diaza-18-crown-6) (1) was mixed with alkali metal perchlorates (MC104; M = Li, Na, K, Rb and Cs). Curved Arrhenius plots for ion conductivity were found for all dry samples, suggesting that ion migration occurs with segmental motion in 1. The potassium cation showed the lowest ion conductivity, reflecting a stronger interaction with the crown ether structure.
