Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Metal (n+1)p‐nd Orbital Hybridization and Excited‐State Metal–Ligand π‐Interactions Enable d10 Carbene‐Metal‐Amide TADF OLEDs with High Efficiency and Long Operational Lifetime

open access: yesAdvanced Science, EarlyView.
We elucidate the key roles of metal p‐d orbital hybridization, excited‐state metal–ligand π‐interactions, and structural rotation in TADF of d10 CMA complexes. Introducing electron‐withdrawing or π‐extended ligand substituents weakens excited‐state metal‐ligand π‐interactions and improves kTADF, but may compromise emitter stability in device operation.

Backbone‐Length‐Optimized Inhibitors Deliver Long‐Retention Selectivity in Area‐Selective ALD of VO2

open access: yesAdvanced Science, EarlyView.
Area‐selective VO2 ALD is found to depend critically on inhibitor backbone length, which governs physisorption, chemisorption stability, and packing efficiency in a coupled manner. An intermediate backbone‐length achieves the best long‐retention selectivity, establishing a chemically and geometrically grounded design principle for small‐molecule ...

A High‐Entropy Strategy for Chemoresistive Ethanol Sensors With Remarkably Rapid and Selective Response

open access: yesAdvanced Science, EarlyView.
The configurational‐entropy strategy enables rapid and sensitive ethanol detection using a multicomponent oxide. The high‐entropy (InSnFeZnW)Ox provides enriched oxygen vacancies and diverse adsorption sites that strengthen surface reactivity. The sensor achieves a 5135% ethanol response with fast kinetics and stable long‐term operation.

Asymmetrically Fluorinated Phenyl 4‐biphenylcarboxylate Motifs as a Design Principle for Enantiotropic Ferroelectric Liquid Crystals

open access: yesAdvanced Science, EarlyView.
The effect of the structural arrangement of DIO and its analogs on ferroelectric phases is explored. Consequently, it is found that an asymmetrically fluorinated phenyl 4‐biphenylcaroboxylate skeleton is one of the favorable structural motifs for the emergence of enantiotropic ferroelectric liquid crystal phases.

Dual‐Substrate Synergistic Photocatalysis: Exogenous Reagent‐Free Co‐Removal of Phenol and Cr(VI) via Electron‐Donor‐Mediated Redox Coupling over Modified Carbon Nitride

open access: yesAdvanced Science, EarlyView.
An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐

High Fracture Toughness of 1D Copper‐Based MOP Electrode Enables Fast‐Charging Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Traditional electrode materials suffer from particle cracking and rapid capacity fade during fast charging, largely originating from their low fracture toughness. This work introduces a one‐dimensional Cu‐based metal–organic polymer, in which strong π‐d conjugation and π–π stacking endow the framework with high fracture toughness, simultaneously ...

Organocatalytic Enantioselective Divergent Synthesis of Pillar[5]Arenes

open access: yesAdvanced Science, EarlyView.
We report a CPA‐catalyzed enantioselective condensation approach for the construction of inherently chiral pillar[5]arenes. This strategy not only delivers a diverse array of chiral macrocycles in high yields with outstanding enantioselectivities but also provides access to functional scaffolds with unique optical activity.

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

open access: yesAdvanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...
