“…With regard to a highly flexible functionalization of surfaces, e.g. in the context of interfacial systems chemistry,1 the deposition of oriented porous materials on appropriately functionalized substrates offers a number of attractive options 2. In particular, metal organic frameworks (MOFs),2–4 are very well suited for such a surface modification, the rendering of specific functions to a coating can be either achieved by loading the MOF material after deposition with functional molecules or by a post‐synthesis modification of the MOF‐constituents 5, 6.…”

We describe a novel method to produce monolithic, oriented, crystalline and highly porous coatings on solid substrates. By adopting the recently described liquid‐phase epitaxy (LPE) process developed to grow metal‐organic framework coatings (MOFs) on modified Au‐substrates to the spray method, we have prepared thick (μm) layers of several MOF types on modified Au‐substrates, including HKUST‐I and layer‐pillar MOFs. The spray method not only allows such SURMOFs to be grown much faster than with the LPE‐process but the dependence of layer thickness on the number of immersion cycles also provides valuable insights into the mechanism governing the layer‐by‐layer MOF formation process.

“…a headgroup for attachment to the substrate, a terminal group that defines the properties of the outer film surface (tailgroup), and a spacer unit that separates the head- and tailgroup and supports the self-assembly process by lateral interactions between adjacent molecules. SAMs have been extensively used to tailor the properties of surfaces as well as for applications in such diverse fields as, for example, nanotechnology [2, 4], molecular electronics [12 – 14], biosensors [2, 15 – 16] and chemical vapour sensing [17]. The archetypal and most commonly used adsorbate system is that of thiols (or closely related reactive sulfur-containing compounds like disulfides or thioacetates) on gold, giving rise to thiolate-type SAMs [4].…”

Thin metalorganic films were prepared on gold by self-assembly of thioether-functionalised phthalocyaninato complexes from solution. The phthalocyaninato ligands used contain eight peripheral, β-positioned, alkylthio substituents SR (1a: R = n-C8H17, 1b: R = n-C12H25), which serve as headgroups for surface binding and promote lateral assembly, while the disk-like phthalocyaninato core offers the scope for the attachment of axial ligands to the adsorbed molecules. This process was mimicked by coordination of pyridine (Py) to [Zn(1a)] and [Zn(1b)], respectively. The crystal structures of the products [Zn(1a)(Py)] and [Zn(1b)(Py)] were determined. The crystal structures of 4,5-bis(octylthio)phthalodinitrile and 4,5-bis(dodecylthio)phthalodinitrile were also determined. The films fabricated from [Mn(1a)Cl] and [Mn(1b)Cl] on gold were characterised by XPS, ToF-SIMS and NEXAFS spectroscopy, which revealed the presence of well-defined and homogeneous self-assembled monolayers (SAMs), whose constituents are bound to the substrate by thioether–gold linkages. The orientation of the macrocycles is predominantly parallel to the surface. Strong electronic interaction of the manganese(III) centre with the substrate leads to Cl loss upon adsorption and its reduction to MnII.

“…Для получения иммобилизованных на поверхности металлоорганических каркасов, ПОВМОК (Surface-Anchored Metal-Organic Frameworks, SURMOFs) используют несколько методов. [9][10][11][12][13][14] Простейший из них состоит в осаждении на подложку частиц МОК, предварительно сформированных в растворе традици-онным сольватотермальным способом. Как правило, перед этим подложка покрывается самоорганизо-ванным монослоем (СОМ) поверхностно-активного вещества, содержащего соответствующие данному МОК функциональные группы.…”
