Abstract

The dielectric properties of the one-dimensional (1D) water clusters confined in the porous crystal, [Co3(2,4-pydc) 23-OH)2].9H2O, were examined. The dielectric constant (ε) decreased abruptly below 200 K, where the first-order phase transition occurred. The results of molecular dynamics simu-lations suggested freezing of the molecular motion of the guest water molecules, forming 1D water clusters at 200 K. ε (10 kHz) increased sharply above 300K and became as high as 500 at 383 K. The hysteresis loop observed at 340 K indicated the antiferroelectric state of the guest water system.
