Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

Chemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

Programming the Optoelectronic Properties of Atomically Precise Gold Nanoclusters Using the Conformational Landscape of Intrinsically Disordered Proteins

Chemistry – A European Journal, EarlyView.
ABSTRACT The rational design of hybrid nanomaterials with precisely controlled properties remains a central challenge in materials science. While atomically precise gold nanoclusters (Au‐NCs) offer molecule‐like control over a metallic core, tuning their optoelectronic behavior via surface engineering is often empirically driven.

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

Chemistry – 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.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

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

Chemistry – 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

Chemistry – 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

Chemistry – 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

Chemistry – 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.
