Synergistic Photophysical and Mechanical Enhancement in Europium Supramolecular Hydrogel by Incorporating Gd(DPA)3 Complex (DPA = Dipicolinate)

ChemistryOpen, Volume 15, Issue 5, May 2026.
Lanthanide‐based hydrogels incorporating Ln(DPA)3 complexes are synthesized and exhibit enhanced mechanical and luminescent properties. Increased complex concentration improves stiffness and emission intensity without altering coordination symmetry. Computational insights reveal preserved structural features, while lifetime changes highlight hydrogel ...

From Molecular Motion to Macroscopic Function: Tailoring Tetraarylethylene Supramolecular Architectures for Aggregation‐Induced Emission and Wave Absorption

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

Acta Crystallographica Section D, Volume 82, Issue 5, Page 457-470, May 2026.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.

From the Modeling of Experiments to the Ab Initio Prediction of Rate Constants: Statistical Rate Theory for a Quantitative Understanding of Gas‐Phase Ion Chemistry

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for

Synthesis, Crystal Structure and Optical Properties of Novel 1,10-Phenanthroline Derivatives Containing 2,6-Diisopropylphenoxy Substituents

Crystals
Two phenanthroline derivatives, 2-(2,6-diisopropylphenoxy)-9-phenyl-1,10-phenanthroline and 2,9-bis(2,6-diisopropylphenoxy)-1,10-phenanthroline, were synthesized. The unsymmetrical derivative was obtained in high yield through a sequence combining Suzuki

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic

Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.

Translocation arrest by reversible folding of a precursor protein imported into mitochondria [PDF]

, 1989
Passage of precursor proteins through translocation contact sites of mitochondria was investigated by studying the import of a fusion protein consisting of the NH2-terminal 167 amino acids of yeast cytochrome b2 precursor and the complete mouse ...
