Highly proton-conductive copper coordination polymers

AC conductivity measurements were carried out for a two-dimensional coordination polymer, N,N'-bis-(2-hydroxyethyl)dithiooxamida-tocopper(II) with an impedance analyzer in order to estimate the protonic conductivity. This polymer was found to exhibit a high protonic conduction of sigma(p) = 1.2 x 10(-5) S cm(-1) under relative humidity of 83% and 300 K. (C) 2003 Elsevier Science B.V. All rights reserved.
