Recently, embedding organic phosphors into the polyvinyl alcohol (PVA) matrix has emerged as a convenient strategy to obtain efficient long‐lived room temperature phosphorescence (RTP) via forming strong intermolecular hydrogen bonds with organic phosphors to minimize nonradiative relaxations. Regrettably, it is discovered that PVA is unable to trigger RTP emission when a novel functional phosphor...
Polymorphic phase transition is an essential phenomenon in condensed matter that the physical properties of materials may undergo significant changes due to the structural transformation. Phase transition has thus become an important means and dimension for regulating material properties. Herein, this study demonstrates the pressure‐induced multi‐transition of both structure and physical properties...
Aqueous rechargeable Zn metal batteries (ARZBs) are extensively studied recently because of their low‐cost, high‐safety, long lifespan, and other unique merits. However, the terrible ion conductivity and insufficient interfacial redox dynamics at low temperatures restrict their extended applications under harsh environments such as polar inspections, deep sea exploration, and daily use in cold regions...
The development of catalytic systems that can activate aryl chlorides for palladium‐catalyzed cross‐coupling reactions is at the forefront of ongoing efforts to synthesize fine chemicals. In this study, a facile ligand‐template approach is adopted to achieve active‐site encapsulation by forming supramolecular assemblies; this bestowed the pristine inert counterparts with reactivity, which is further...
Heterostructured materials integrate the advantages of adjustable electronic structure, fast electron/ions transfer kinetics, and robust architectures, which have attracted considerable interest in the fields of rechargeable batteries, photo/electrocatalysis, and supercapacitors. However, the construction of heterostructures still faces some severe problems, such as inferior random packing of components...
The urgent demand for high energy and safety storage devices is pushing the development of lithium metal batteries. However, unstable solid electrolyte interface (SEI) formation and uncontrollable lithium dendrite growth are still huge challenges for the practical use of lithium metal batteries. Herein, a composite polymer electrolyte (CPE) endowed with designated ion channels is fabricated by constructing...
Aqueous zinc–ion batteries typically suffer from sluggish interfacial reaction kinetics and drastic cathode dissolution owing to the desolvation process of hydrated Zn2+ and continual adsorption/desorption behavior of water molecules, respectively. To address these obstacles, a bio‐inspired approach, which exploits the moderate metabolic energy of cell systems and the amphiphilic nature of plasma...
Carbonized Polymer Dots
In article number 2106863, Yeqing Chen, Ping Liang, Jun Lin, and co‐workers synthesize transition metal Mn ions doped in the form of covalent Mn–O bonds. The Mn–O bridge accelerates the electron flow between adjacent sp2 domains and enhances the electron transport in the Mn–carbonized polymer dots, thus improving the photoluminescence quantum yield and catalytic performance...
Carbonized polymer dots (CPDs) have received tremendous attention during the last decade due to their excellent fluorescent properties and catalytic performance. Doping CPDs with transition metal atoms accelerates the local electron flow in CPDs and improves the fluorescent properties and catalytic performance of the CPDs. However, the binding sites and the formation mechanisms of the transition‐metal‐atom‐doped...
Zinc metal is an ideal candidate for aqueous rechargeable batteries due to its high theoretical capacity and natural abundance. However, its commercialization is inevitably challenged by several critical factors such as dendrite growth and parasitic side‐reactions, leading to low coulombic efficiency and a limited lifespan. Herein, a modified Zn foil with a zincophilic ZnSe layer deposited by a simple...
As a new member of 2D materials, 2D tellurium (Te) has recently attracted much attention due to its intriguing properties. Through hydrothermal processing, 2D Te with tunable thickness and size has been realized, and its growth mechanism has also been studied. However, the tailored growth of 2D Te nanoflakes with symmetrical morphologies and interfacial moiré fringes has never been reported. Here,...
In article number 2000228, Luying Li, Tianyou Zhai, and co‐workers prepare large‐size BiOCl flakes with thickness down to a monolayer via salt‐assisted chemical vapor deposition. The 2D BiOCl photodetectors exhibit high responsivity throughout the solar‐blind range at room and high temperatures. The success in fabrication of atomically thin BiOCl photodetectors opens opportunities for their potential...
2D wide‐bandgap semiconductors demonstrate great potential in fabricating solar‐blind ultraviolet (SBUV) photodetectors. However, the low responsivity of 2D solar‐blind photodetectors still limits their practical applications. Here, high‐responsivity solar‐blind photodetectors are achieved based on 2D bismuth oxychloride (BiOCl) flakes. The 2D BiOCl photodetectors exhibit a responsivity up to 35.7...
