04 Oct: STRUCTURAL FLEXIBILITY AND VERTICAL CHARGE TRANSPORT IN SCO ULTRATHIN FILMS

Our study of the nanoscale properties of a family of 2D FeII Hoffmann-like coordination polymers was just published as an article in Chemistry of Materials. This collaboration between from FuniMat and SMolMat research groups of the ICMol, and scientist from the DELTA synchrotron of TU Dortmund. We report the fabrication of ultrathin films of (thickness < 30 nm) of this family of 2D FeII Hoffmann-like coordination polymers, and the subsequent study of their electronic and structural properties at the nanoscale. This type of study is unprecedented in spin crossover coordination polymers and contributes to the perspective integration of these materials into the field of electronics.

04 Oct: NONPLANAR PRECURSORS TO PRODUCE WAVY COFs

Check our last collaboration with Mateo-Alonso´s group in Polymat. Marta-COF-1 is a nonplanar 2D-COF in which the waviness of the framework does not disrupt the interlayer p-p stacking so their charge transporting properties are similar to those of the best performing planar 2D COFs. The high stability and crystallinity of Marta-COF-1 have allowed an extraordinary level of characterization by HR-TEM, showing chairlike honeycomb facets and aligned mesoporous channels consistent with the experimental and predicted dimensions and packing.

04 Oct: HELLO TO HYDROXAMATE FRAMEWORKS

Natalia´s work is already available at JACS. The design of metal–organic frameworks with chemical stability is limited to metal connectors as carboxylates or azolates. Inspired by the chemistry of siderophores, we report a hydroxamate titanium framework that combines photoactivity with hydrolytic stability. The straightforward derivatization of carboxylic linkers with hydroxamic groups might represent an alternative route to broaden the family of reticular solids. Check it out!
