Surface-Anchored Metal-Organic Frameworks (SURMOFs)

KNMF Laboratory for Micro- and Nanostructuring

Availability limited to KIT internal users (starting 25th call)

SURMOFs represent a new class of highly porous and highly crystalline materials that may be used as host structures for molecules or nanoparticles with high application potential in gas storage systems, optical sensors, or catalytically active materials, to name a few examples. Metal-Organic Frameworks (MOFs) - in general - consist of two main components: metallic nodes and organic linker molecules. An automated layer-by-layer (LBL) deposition procedure [1] allows to deposit the metal compound and the linker molecules in an alternating fashion on chemically functionalized substrates (oxides, gold-coated substrates). The thickness of the layers is determined by the number of synthesis cycles while the size and chemical properties of the SURMOFs are defined by the used linker molecules. Different methods, e.g. spray or dip coating, are available for the SURMOF preparation. The application of additional treatments (e.g. ultrasonication), results in SURMOFs with high optical quality and high transparency. [2]

In contrast to MOF thin films prepared from powders deposited on substrates by painting or doctor-blade techniques, the SURMOFs are monolithic, highly oriented and exhibit a low density of defects. Due to these outstanding properties SURMOFs can be used not only as model system for studying crucial intrinsic properties of MOF materials, including diffusion of guest species and the formation of surface barriers (see [3] as a review) but also as model host substrates for nanoparticles [4] or molecules to investigate e.g. diffusion processes [5] or charge transport behavior [6]. After fabrication, SURMOFs are characterized by X-Ray diffraction (XRD, to verify crystallinity and growth orientation) and by IR reflection absorption spectroscopy (IRRAS, for chemical characterization).
