Abstract Scope |
Metal-organic-framework (MOF) films are designed scaffold-like compounds consist of metal ions connected by organic ligands, forming highly ordered porous structures. Recently, it has been reported that the electrical properties of bulk host MOFs can be modulated by infiltrating guest molecules (metal clusters) inside the porous MOF framework. In this work intrinsic non-doped highly oriented Surface Anchored Metal-Organic Framework (SURMOF) films were fabricated quasi-epitaxial and benchmarked against doped MOF films loaded with tetracyano-quinodimethane (TCNQ) infiltration. MOF films of Cu3(BTC)2 (BTC: benzene tri-carbonicacid), known as HKUST-1, have been grown using a liquid phase epitaxy (LPE) spray method in which the metal-containing solution [1 mmol Cu(OAc)2] and the linker solution [0.1 mmol BTC] are sprayed alternately on modified silicon substrates. Subsequently, the samples were immersed into an ethanoic TCNQ solution. In this study microwave broadband dielectric spectroscopy has been applied to investigate radio frequency propagation characteristics in pristine versus TCNQ infiltrated SURMOF films. |
