Metal-organic frameworks (MOFs) are an interesting class of nanoporous crystalline solids that can be readily self-assembled by combining metal ions (or clusters) and multitopic organic ligands via coordination bondings. Often characterized by well-defined nano-porosity and large internal surface area, MOFs are being examined as candidates for applications in chemical separations, gas storage, ionic conduction, and chemical sensing. In particular, electronic or ionic conductive MOF materials have shown considerable potential for their conceivable applications in i.e., electrical and electrochemical devices. But, such applications are typically based on the platform of films. Thus, the fabrication of MOF films has been thought as an essential step prior to the applications. To date, several methods for synthesizing MOF film have been suggestedsurface modification and subsequent primary (or direct) growth, spin-coating, electrochemical deposition, alternating Layer-by-Layer (LBL) growth, and Langmuir-Blodgett deposition. These fabrication methods are often combined with the chemical functionalization of substrate surface in order to enhance the adhesive force in the junction between MOF film and metal substrate and thereby, synthesize chemically robust MOF film on the metal. However, it has proven difficult to enhance the adhesive force because the covalent bond formed by the functionalization is not strong as well enough to bind the film, or the adhesion force is weak physical interaction unless the substrate is not functionalized. In addition to this, the film will be substantially robust if MOF crystal domains are crossly interconnected. Due to the lack of strong adhesive force and chemical link between domains, however, MOF films are often peel off from the metal substrates. Thus, the synthesis of robust MOF films can be feasible when these two factors are considered. In this poster, we present a successful method to synthesize robust HKUST-1 films on metallic Cu substrate. The fabrication could be achieved by soaking Cu substrate into a prepared solution only for 5 min. Further, we demonstrate that this method is highly useful for fabricating patterned MOF films.
