Mesoscale Hybridization Strategy for Organic Supramolecular Assemblies and Inorganic Semiconductor Nanocrystals

Abstract Supramolecular polymers (SPs) are noncovalently formed molecular assemblies that have been actively studied in terms of molecular design, self-assembly processes, and morphological control. SPs programmed via surface modification can serve as outstanding mesoscale scaffo...

Modulation of Open-Shell Character in Dibenzoazaborine Dications through Amino-Substituent Modification

Abstract Oxidation of dibutylamino-substituted dibenzoazaborine Bu2NDBAB afforded the air-stable dication [Bu2NDBAB](SbF6)2 in 83% yield, with an NIR absorption band at 943 nm. Structural analysis revealed pronounced oxidation-induced quinoidal distortion. Unlike the previously r...

Ultrafast Nuclear Rearrangement Governs Excited‐State Radial π‐Conjugation and Electron Transfer Dynamics in Organic Nanoring

ABSTRACT Radial π‐conjugation provides a unique platform for extending electronic delocalization in cyclic molecular architectures. Although radial π‐conjugation is relatively robust against static disorders in the ground state, both theoretical and experimental observations indi...

Tunable thermochromism of VO2 on SiO2/Si in the visible region

Vanadium dioxide (VO2) undergoes an insulator-to-metal phase transition above room temperature, across which the optical transmittance changes dramatically in the infrared region. In contrast, the transmittance modulation in the visible region is limited. Thus, VO2 exhibits visib...

Crystallographic Spin‐Orbit Torque From Epitaxial CrSb

ABSTRACT Altermagnets (AMs) represent an emerging magnetic phase that combines compensated antiferromagnetic order with ferromagnet‐like spin‐splitting, offering a new route for efficient spin‐current generation. Here, we experimentally demonstrate spin‐torque generation in epita...

Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films

Rare-earth-free ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial NiCo2O4 (NCO) thin films by the time-resolved magneto-optical Faraday effect using two independ...
