Liquid Crystalline Self‐Assembly with Accelerated Kinetics and Higher Structural Orderliness in Centrifugal Acceleration Fields Beyond 7251 Times Gravity of Earth

Advanced Science, EarlyView.
How do chemical and physical processes involving multiple phases develop on compact astrophysical objects such as white dwarf stars? Herein, entropy‐driven self‐assembly of rod‐shaped nanoparticles in centrifugal acceleration fields up to 7251 times the gravity of Earth is investigated, where strong acceleration fields accelerated the kinetics of phase

Time‐Resolved Dynamics of Laser Ablation in Liquid with Gas‐Evolving Additives: Toward Molding the Atomic Structure of Nonequilibrium Nanoalloys

Advanced Science, EarlyView.
Laser ablation in liquid still holds great potential for the synthesis of multicomponent non‐equilibrium nanomaterials. Here, time‐resolved experiments reveal that gas‐evolving additives both have chemical effects and reduce shockwave pressure. This approach offers a strategy to control the atomic structure of the nanoalloys, easily switching from ...

Pyridine‐Fused Bis(azacorrole)s: Easily Accessible NIR III Absorbing Cation Radicals and Biradicaloids of Antiaromatic Ground State

Advanced Science, EarlyView.
A series of pyridine‐fused hetero‐ and homodimers containing azacorrole moiety is obtained. The spectral, redox, and magnetic properties of the bis(azacorrole)s reflect an electron‐donating character of these systems and interaction between the subunits which depends on the substitution pattern.

Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

Advanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.
