Beschreibungen/Notizen

• A robust and low dielectric 3D metal–organic framework [Mg(phen)(bdc)]n (1; phen = 1,10‐phenanthroline, bdc2– = 1,4‐benzenedicarboxylate) was hydrothermally synthesized from magnesium acetate, H2bdc, and phen ligands. Compound 1 has a non‐interpenetrated network with an uncommon cds‐type topology. Chemical and dielectric investigations of this material indicate that it retains a high chemical stability and has a low dielectric constant of 3.33 ± 0.1 (at 100 kHz), which is the lowest value for Mg‐based MOFs reported to date. In addition, temperature‐dependent dielectric studies revealed that its low dielectric constant is retained over a wider temperature range. Mg‐based MOFs have the advantage of being a new class of dielectric materials because of their many intrinsic properties. A 3D, robust, and low dielectric (low‐κ) Mg‐based MOF with a non‐interpenetrated cds‐type topology was prepared. Dielectric measurements revealed the κ value to be 3.33 ± 0.1 (at 100 kHz). It is evident that the incorporation of alkaline‐earth metal ions in highly porous frameworks could result in materials with low‐κ properties.
