Coordinatively unsaturated metal sites (open metal sites) in metal-organic frameworks: design and applications

Ü. Kökçam-Demir, A. Goldman, L. Esrafili, M. Gharib, A. Morsali, O. Weingart, C. Janiak,

Chem. Soc. Rev. 2020, 49, 2751-2798.


The defined synthesis of OMS in MOFs is the basis for targeted functionalization through grafting, the coordination of weakly binding species and increased (supramolecular) interactions with guest molecules.
Encapsulation of a Porous Organic Cage into the Pores of a Metal-Organic Framework for Enhanced CO2 Separation

J. Liang, A. Nuhnen, S. Millan, H. Breitzke, V. Gvilava, G. Buntkowsky, C. Janiak,

Angew. Chem. Int. Ed. 2020, 59, 6068-6073.


A facile ‘host-in-host’ approach has been utilized to prepare functional porous organic molecule based hybrid materials by encapsulating cucurbit[6]uril (CB6) cages into the nanospace of a metal-organic framework (MOF). The obtained CB6@MIL-101 composites were shown to be efficient porous adsorbents with enhanced CO2 uptake capacity and CO2/N2, CO2/CH4 separation at low pressures.

Metal–organic frameworks (MOFs) currently receive high interest for cycling water adsorption applications like adsorption heat transformation for air-conditioning purposes. For practical use in adsorption heat pumps (AHPs) the microcrystalline powders must be formulated such that their high porosity and pore accessibility is retained. In this work, the preparation of millimeter-scaled pellets is reported by applying the freeze granulation method. The use of poly(vinyl alcohol) (PVA) as binder reproducibly resulted in highly stable, uniformly shaped PVA/MOF pellets with 80 wt% MOF loading, with essentially unchanged MOF porosity properties after shaping. The shaped pellets were analyzed for the application in AHPs by water adsorption isotherms, over 1000 water adsorption/desorption cycles and thermal and mechanical stability tests. Further, the pellets were applied in a fixed-bed, full-scale heat exchanger, yielding specific cooling powers from 349 up to 431 W/kg(adsorbent), which outperforms current commercially used silica gel grains in AHPs under comparable operating conditions.

Facile in Situ Halogen Functionalization via Triple-Bond Hydrohalogenation: Enhancing Sorption Capacities through Halogenation to Halofumarate-Based Zr(IV)-Metal-Organic Frameworks

T. J. Matemb Ma Ntep, H. Breitzke, L. Schmolke, C. Schlüsener, B. Moll, S. Millan, N. Tannert, I. El Aita, G. Buntkowsky, C. Janiak

Chem. Mater. 2019, 31, 8629–8638.


The halogen groups in the Zr-MOF materials result in increased hydrophilicity for water vapor sorption, as well as increased uptakes by 21% SO2, 24% CH4, 44% CO2, 154% N2 when compared to the non-halogenated MOF-801.

Designing a new aluminium muconate metal-organic framework (MIL-53-muc) as methanol adsorbent for sub-zero temperature heat transformation applications;

T. J. Matemb Ma Ntep, H. Reinsch, P. P. C. Hügenell, S.-J. Ernst, E. Hastürk, C. Janiak 

J. Mater. Chem. A 2019, 7, 24973–24981. 


Employing methanol as adsorbate can enable adsorption-driven heat pumps and chillers to operate at/or achieve temperatures below 0 °C, provided the appropriate pairing adsorbent is made available.
Solid-Solution Mixed-Linker-Synthesis of Isoreticular Al-based MOFs for an Easy Hydrophilicity Tuning in Water-Sorption Heat Transformations; Humidity Control;

C. Schlüsener, M. Xhinovci, S.-J. Ernst, A. Schmitz, N. Tannert, C. Janiak,

Chem. Mater. 2019, 31, 4051-4062.


We use and demonstrate here the "solid-solution" mixed-linker approach (defined as variation of two linker proportions) as an easy and inexpensive way to fine-tune the hydrophilicity properties of isoreticular MOFs. The water uptake region was easily shifted in between the limits set by the two single-ligand MOFs.

Cryst. Growth Des. 2019, 19, 2869-2880[488pdf-file]


The new isostructural porous supramolecular materials {[Cu2(amp)4Cl][M(C2O4)3]·6H2O}n show good potential to be used for automatic indoor control in the range of 15 to 25% r.H. recommended for many activities.
