A low-κ dielectric metal–organic-framework compound showing novel three-step dielectric relaxations originating from orientational motion of dipolar guest molecules†
Abstract
A three-dimensional metal–organic framework compound with a formula [Cu2(EBTC)(H2O)2·8H2O·DMF·DMSO]∞ (EBTC = 1,1′-ethynebenzene-3,3′,5,5′-tetracarboxylate) shows novel three-step dielectric relaxations arising from the orientational motion of dipolar guest molecules and its guest-free framework displays low-κ dielectric permittivity.
