The low dielectric constant and relaxation dielectric behavior in hydrogen-bonding metal–organic frameworks†
Abstract
A 3D supramolecular hydrogen-bonding metal–organic framework with the formula [Zn(CEIC)2(H2O)]·2DMF (CEIC = 4-carboxy-2-ethyl-1H-imidazole-5-carboxylate) was reported, which is a very rare example with a low dielectric constant value at high temperature for MOFs with solvent molecules. The novel dielectric relaxation of this compound was observed.
