Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

open access: yesSmall, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

A Novel Approach to Integrate Differential Modulation With OTFS Systems Over mmWave UAV Channels

open access: yesIEEE Access
Orthogonal time frequency space (OTFS) modulation designed for highly dynamic millimeter-wave (mmWave) channels, has the advantage of converting time-varying channels into quasi-static representations in the delay–Doppler (DD) domain, making it ...

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Hydrogen Bond Mediated Dioxygen Activation in a Manganese Guanidine Complex

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The guanidine arms of [Mn(DIG3tren)]2+ provide the reducing equivalents and H‐bonding stabilization necessary for the bimolecular activation of O2 to form a mixed valent MnIII(m‐O)2MnIV species. A high‐spin manganese(II) complex supported by a guanidine‐based DIG3tren (tris(N’, N”‐diisopropylguanidinyl‐2‐ethyl)amine) ligand has been synthesized and ...

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...

Synthesis of Arylsilanes by Catalytic Silylation of C(sp2)─X Bonds: A Review From the Silicon Perspective

open access: yesAsian Journal of Organic Chemistry, Volume 15, Issue 7, July 2026.
This review surveys the synthesis of arylsilanes by catalytic silylation of C(sp2)−X bonds from an original silicon perspective. By categorizing methodologies based on the philicity of the silylating reagents, moving from abundant electrophilic silicon sources to more specialized nucleophilic ones, it highlights the structural diversity of silyl groups
