Boron Monofluoride Complexes Bearing π‐Expanded Coumarin Subunits: Facile Synthesis, Crystal Structure, and Solid‐State Enhanced Emission

Chemistry – A European Journal, EarlyView.
We here report the design, facile synthesis, experimental, and theoretical characterization of a novel class of monofluoroborate compounds featuring π‐expanded coumarin subunits displaying solid‐state enhanced Emission. The origin of this phenomenon is disclosed by combined theoretical and spectroscopic investigations.

Synthesis, Structures, and Properties of Cyclopenta‐Fused Anthra[1,2‐a]anthracene Derivatives as New Polycyclic Aromatic Compounds

Chemistry – A European Journal, EarlyView.
Three new polycyclic aromatic compounds consisting of one or two five‐membered rings were synthesized by Scholl reaction or Pd‐catalyzed cyclization from fused anthracene derivatives. X‐ray analysis and DFT calculations revealed that these compounds have slightly twisted or curved structures.

Asymmetric Activation of Tropos Biphenolic Moieties by Isohexides: An Integrated Computational‐Experimental Approach

Chemistry – A European Journal, EarlyView.
The integrated experimental‐computational study on the asymmetric activation exerted by isohexides on tropos tetra‐aryl moieties embedded in a chiral macrocyclic architecture resulted in a complete definition of the stereochemical as well as stereodynamic features of the macrocyclic final compounds.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle

Cytoskeleton, EarlyView.
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

Synergistic Molecular Engineering and Crosslinking Topology for High‐Temperature Energy Storage in All‐Organic Dielectrics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic strategy combining CF3 group incorporation and crosslinking topology is employed to tailor chain spacing and local ordering in all‐organic dielectrics. This design effectively suppresses carrier migration and enhances polarization, yielding outstanding high‐temperature energy storage performance (e.g., 8.95 J cm−3 with 90% efficiency at ...

Dimensional Engineering of Wet‐Spun MOF‐Based Woven Fabrics for Superior Electromagnetic Wave Absorption

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...
