Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

Chemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Hydrogen Release From Silicon─Hydrogen Systems: From Surface Chemistry to Higher‐Coordinate Molecular Mechanisms

Chemistry – A European Journal, EarlyView.
Hydrogen‐release processes in silicon chemistry occur across a broad spectrum of systems, including crystalline silicon surfaces, nanoporous materials, Zintl phases, and molecular hydrides. This Review highlights how Si─H activation and H2 evolution are governed by structure, coordination environment, and dynamic access to reactive geometries, with ...

Synthesis and Photophysical Properties of Star‐Shaped Triphenylamine Trimers Functionalized With BODIPY and Subphthalocyanine Chromophores

Chemistry – A European Journal, EarlyView.
This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

Chemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected

Encapsulation of Linear and Cyclic Alkanes in Water Within a Dimeric Deep‐Cavity Sulfonatocalix[4]arene Capsule

Chemistry – A European Journal, EarlyView.
Captured in water. A tetrasulfonated deep‐cavity calix[4]arene encapsulates linear and cyclic alkanes, as well as benzene and hexafluorobenzene, in water by forming a self‐assembled dimeric capsule. The binding affinity is guest size‐dependent. For linear alkanes, the affinity peaks at n‐hexane, while cyclooctane is the most strongly bound cycloalkane.
