Dielectric Properties of Water Chains Incorporated in Porous Coordination Polymer Crystal [Cu(C6H4NO2)2

Abstract

Abstract The dielectric constant (ε) of “water chains” incorporated in the channel of porous coordination polymer crystal [Cu(C6H4NO2)2] was small at low temperatures (ε ≈ 10) but became as large as 250 at 370 K. These dielectric behaviors were consistent with the results of molecular dynamics simulation and indicated that a melting of hydrogen-bonded water chains occurred above 300 K.
