Fabrication of Oriented Polycrystalline MOF Superstructures

PMWS associate ECRs Mercedes Linares-Moreau, Miriam Velásquez-Hernández, Lea Brandner, Prof. Falcaro, and researchers from University of Vienna (Prof. Chin group), Catalan Institute of Nanoscience and Nanotechnology (Prof. Maspoch group), and The University of Adelaide (Prof. Doonan) have recently published an Invited Perspective article in Advanced Materials focused on emerging oriented MOF superstructures. The perspective examines the advantage, the challenges, and the recent fabrication approaches for the preparation of oriented polycrystalline MOF superstructures. While the advantage is the exploitation of anisotropic functional properties in MOF-based devices, the challenges include the need for customized self-assembly procedures to enable the precise orientation of each individual crystal. Colloidal assembly, external fields, heteroepitaxial ceramic-to-MOF, and other emerging methods are discussed. By covering nearly 300 articles, the perspective aims to provide a critical view of the field and promote the development of systems with oriented pore channels

Fabrication of 3D Oriented MOF Micropatterns with Anisotropic Fluorescent Properties

PMWS associate ECRs Miriam De Velásquez-Hernández, Mercedes Linares Moreau, and Francesco Carraro published together with an international team of reseachers from TU Graz, KU Leuven, U Friborg, and U Adalaide a MOF patterning protocol published in  Advanced Materials that allows to immobilize and align fluorescent guest-molecules within the MOF pores. They used deep X-ray Lithography for the fabrication of 3D oriented MOF micro-patterns. MOF films with X-ray sensitivity were obtained by using a mixed linker strategy, integrating a brominated dicarboxylic ligand (Br2BDC) into a copper-based MOF Cu2L2DABCO (L=BDC/Br2BDC). The MOF film was obtained via heteroepitaxial growth from a sacrificial layer of oriented Cu(OH)2 nanobelts, thus affording 3D oriented MOF crystals. Immobilization and alignment of the fluorescent guest-molecules in the MOF pores is evidenced by rotating the polarization angle of the laser excitation in Fluorescence Microscopy. By controlling the functional response to light, this MOF patterning protocol could be used for the microfabrication of optical components for photonic devices. 

Tuning the surface properties of nanopores

Egbert Zojer, key researcher in Porous Materials@Work for Sustainability, disclosed how to tune the surface electronic structure of nanopores in covalent organic frameworks. The key idea is to decorate the pore surfaces with dipolar groups, which collectively lift or lower electronic states in energy at the pore surface and in the pore. The work is published in Nano Letters.

New copper isonicotinate polymorph in vapor-deposited thin films

Researchers from the KU Leuwen and from Porous Materials@Work for Sustainability revealed a new polymorph of a Copper Isonicotinate MOF, that is found in chemically vapor-deposited thin films. Crystalline order in such films is strongly influenced by the precursor layer. Their work published in Advanced Materials and Interfaces introduces how the combination of GIXRD data with Patterson functions can be used to identify the structure of an unknown thin-film MOF polymorph.

Making porous current collectors for batteries

Researchers from the National Institute of Chemistry Ljubljana, Varta Innovation GmbH and Porous Materials@Work for Sustainability disclosed a way of preparing conducting macroporous carbon coatings on conductive substrates. The work published in Monatshefte für Chemie is focusing on the preparation of poly(dicyclopentadiene) derived porous conductive coatings on metal foils and their scope and limitation when used as binder free current collector in lithium-sulfur cells.

Porphyrinic MOFs for oxygen sensing: Mirror, mirror on the wall, who's the most sensitive of them all?

A group of researchers from the Porous Materials@Work for Sustainability consortium uncovered the structure sensitivity relationship in porphyrinic zirconium-organic frameworks when used for optical oxygen sensing. The paper in ACS Applied Nano Materials establishes an oxygen sensitivity trend increasing in the order PCN-222 < PCN-223 < PCN-224. High sensitivity is above all caused by a maximized porphyrin−porphyrin separation in these nanostructured materials, which results in an increase of the fluorescence decay time, which, in turn, increases the probability of the quenching event. Defects in the nanostructure are another factor explaining variations in sensitivity within the same MOF type prepared with varying reaction conditions. Properly grown PCN-224 crystals show the highest sensitivity ever reported for a porphyrin based oxygen sensing material.

On the nanoscale structural evolution of solid discharge products in lithium-sulfur batteries using operando scattering

High-performance lithium-sulfur (Li₂S) batteries with non-aqueous electrolyte solutions require a sound understanding of the conversion between Li-S and molecular surfur.
Researchers around C. Prehal, S. Freunberger, and V. Wood now demonstrate together with the PM@WS key researcher H. Amenitsch in their recent article that in-operando small-angle and wide-angle X-ray scattering and small-angle neutron scattering reveal how nucleation, growth and dissolution of solid deposits from atomic to sub-micron scales evolve during real-time Li-S cell operation.

A Free Web-App for the quantification of crystal phases in ZIF biocomposites

Depending on the preparation conditions, the addition of Zn cations and 2-methylimidazole to biomolecules often yields azolate frameworks bio-composites with different crystalline phases/topologies. PMWS associate ECRs Michael Hafner, Laura Villanova, and Francesco Carraro designed a free web-app that analyses XRD diffraction patterns. As outputs, the web-app 1) identifies the major crystalline components and 2) quantifies their amount. As zinc-based azolate frameworks with different crystalline phases have different functional properties, this web-app will facilitate the exploration and the design of MOF biocomposites with customized properties. The invited paper is part of a “New Talent 2022” themed collection on CrystEngComm (RSC). The web-app paper was highlighted with the front cover journal.

Carbon foams from emulsion templated poly(dicyclopentadiene)

PM@WS researcher Christian Slugovc shows in his new article together with researchers from National Institute of Ljubljana, Varta Innovation GmbH, Institute of Science and Technology Austria and ICTM (TU Graz) that Ring-opening Metathesis Polymeriziation derived poly(dicyclopentadiene) foams are ideal precursors for the preparation of hierarchically porous carbon foams. The unique feature of the foams is that fixation necessary to retain the foam’s structure during the carbonization step is performed at very mild and sustainable conditions (oxygen from air, 40 °C). Upon carbonization foams with a carbon content higher than 97 %, an electronic conductivity of up to 2800 S·m–1, a Young’s modulus of up to 2.1 GPa, and a specific surface area of up to 1200 m2·g–1 were obtained. The 3D interconnectivity of the macroporous precursor foams was fully preserved and carbon foams with average void diameters between 87 and 2.5 μm can be prepared. Finally, the carbon foams were applied as porous cathodes for Li–O2 batteries. The favorable combination of active surface area and macropore sizes led to outstanding discharge capacities 10 fold higher than obtained with Super P based cathodes.
