Self‐assembly and Lateral Cobalt Coordination of a Fivefold Symmetric Cyanostar Macrocycle on an Au(111) Surface

open access: yesChemistry – A European Journal, EarlyView.
Herein, we report the first example of the formation of a close‐packed, regular 2D monolayer of a fivefold symmetric cyanostar macrocycle on an Au(111) surface under ultra‐high vacuum and the structural modification of such self‐assembled architecture upon cobalt atom deposition.

Self‐Assembled Luminescent Au(I)–Adamantylamine Coordination Polymer Needles With Thermoresponsive Optical Properties

open access: yesChemistry – A European Journal, EarlyView.
A self‐assembled hydrophobic and red phosphorescent Au(I) coordination polymer (CP) was synthesized under mild conditions. Single‐crystal X‐ray diffraction (XRD) demonstrated linear Au(I) chains stabilized by aurophilic and hydrogen bonding interactions.

Preparing an Exsolvable Ru‐Substituted LaFeO3 Perovskite With High Surface Area From a Self‐Sacrificial Polymer Template: A Versatile Strategy for Enhanced Catalytic Performance

open access: yesChemistry – A European Journal, EarlyView.
High‐surface‐area LaFe0.9Ru0.1O3 is prepared by infiltration of porous Amberlite XAD16 polymer beads. Ru exsolution of this perovskite material leads to a supported catalyst with small Ru particles, exhibiting promising catalytic performance propane combustion.

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

open access: yesChemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF

open access: yesChemistry – A European Journal, EarlyView.
Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.
