Solvothermal growth of a ruthenium metal–organic framework featuring HKUST-1 structure type as thin films on oxide surfaces

Abstract

Phase-pure crystalline thin films of a mixed-valence Ru(2)(II,III) metal-organic framework with 1,3,5-benzenetricarboxylate (btc) as a linker were solvothermally grown on amorphous alumina and silica surfaces. Based on the Rietveld refinement, the structure of Ru-MOF was assigned to be analogous to [Cu(3)(btc)(2)] (HKUST-1).

Investigation of the synthesis, activation, and isosteric heats of CO2 adsorption of the isostructural series of metal–organic frameworks M3(BTC)2 (M = Cr, Fe, Ni, Cu, Mo, Ru)

“…Our attempts to synthesize Ru 3 (BTC) 2 starting from RuCl 3 ·xH 2 O or Ru 2 Cl(μ-OAc) 4 according to literature procedures yielded either amorphous products or poorly crystalline materials. 54 Increasing the reaction temperature above that reported in the 60 literature produced significant amounts of Ru metal. However, employing Ru 2 Cl(μ-OPiv) 4 (OPiv = -O 2 C─C(CH 3 ) 3 ) as the ruthenium source afforded material with a higher degree of crystallinity ( Figure S8).…”

Extension of the Universal Force Field for Metal–Organic Frameworks

“…The 18 UFF4MOF parameters introduced, therefore facilitate calculation of a vast number of common and important MOFs, however, an increasing number of frameworks are being synthesised using heavier elements, including Palladium, 51 Silver 52-54 and Ruthenium. 55,56 It is clearly desirable to be able to calculate these structures rapidly, either post-synthesis or in predictive calculations. A force field that can accurately predict structures of a broad range of metal containing building blocks would allow such building blocks to be used in predicting the structures of hypothetical MOFs 57 using software such as AuToGraFS 58 or Zeo++.…”

Metal–organic framework growth at functional interfaces: thin films and composites for diverse applications

“…Consequently there are now a growing number of reports of methods to prepare MOF thin films or coatings, nanoparticles 55 (nps) and composites, which have been recently reviewed. 20,21 The aim of these studies is to take MOFs beyond interesting crystals full of promise on the laboratory bench-top, and prepare or process these (directly or otherwise) into integrated devices and other application-specific configurations required for 60 commercialisation and by the future end-users of the product. This is a necessary step for MOFs, marking the next phase of their development and moving the research field into its adolescence.…”

“…2) on functionalised SAMs on Au substrates. 33,37 The MOF precursor solutions are prepared by dissolution of the metal ions and ligands into the bulk reaction solvent and held at elevated temperature to initiate the formation of MOF nuclei; the 60 solutions are subsequently cooled, and filtered if required, prior to SAM immersion. Hermes et al used micro-contact printing to form a grid-like 70 patterned SAM consisting of -CO 2 H terminated squares separated by inert -CF 3 terminated lines.…”
