Metal lead halide perovskite quantum dots (PeQDs) exhibit exceptional optoelectronic properties, showing promise as components for solar cells, lighting, display, and anticounterfeiting devices. However, the instability of PeQDs, along with synthesis and storage methods that rely on hazardous solvents, has limited their potential for commercial applications. To overcome these obstacles, we introduce a solvent-free method for fabricating high-quality green and red CsPbX 3 PeQD (X = Br, I) ink. Using a fluidic system, we first obtained super-high photoluminescence quantum yield PeQDs (92 % for red CsPb(Br,I) 3 , and nearly 100 % for green CsPbBr 3 PeQDs). The uniform nonsolvent PeQD ink is fabricated by modifying the as-formed PeQD surface with a mixture of trimethoxysilane and 3-(trimethoxysilyl)propyl methacrylate silane coupling agents to form PeQDs@silane, then dispersing the PeQDs@silane in a UV-curable 1,6-hexanediol diacrylate monomer. Our solvent-free PeQD ink exhibits bright and stable green and red emissions with long-term stability, retaining 100 % PL intensity after 115 days for CsPbBr 3 and 78 days for CsPb(Br,I) 3 . The environment-friendly ink enables highly uniform and bright films for LED backlighting and patterns for micro-LED applications. With color coordinates near the red and green reference values, the PeQD films demonstrate a remarkable 100.28 % color gamut coverage in comparison with Rec. 2020. This scalable and environmentally friendly method provides a safer alternative than conventional solvent-based PeQD ink.

Thienyl Chloride Initiated Living Cationic Polymerization: A General and Efficient Access toward Terminally Functionalized Poly(vinyl ether)s

Macromolecules 2020年第5期53卷 1536-1542页

作者： Lu Zhang Kunming Jiang Xianwang Shen Yu Gu Xinrong Lin Mao Chen Key Laboratory of Medicinal Chemistry for Natural Resource Ministry of Education and Yunnan Province School of Chemical Science and Technology Yunnan University Kunming 650091 China State Key Laboratory of Molecular Engineering of Polymers Department of Macromolecular Science Fudan University Shanghai 200433 China

Poly(vinyl ether)s (PVEs) are useful materials of different applications. In this work, we have developed a versatile and highly efficient initiation approach based on thienyl chloride derivatives with readily available starting materials for the living cationic polymerization of vinyl ethers. The resulting polymers exhibited precise chemical structures, predetermined molecular weights, and narrow molecular weight distributions at complete monomer conversions, allowingin situchain extension to give diblock copolymers in several minutes. The synthetic advances of this method enable highly efficient connection of aryl, benzyl, and alkyl groups, as well as other functional substituents onto PVEs’ terminals, and also facilitate the preparation of di-end-functional polymers. Furthermore, the high chain-end fidelity allows post-synthetic modifications through diverse pathways, such as RAFT polymerization, photocontrolled radical polymerization, Ni-catalyzed Negishi cross-couplings, and Pd-catalyzed Suzuki–Miyaura cross-couplings. While the incorporation of PVEs could bring macromolecules interesting properties, this method provides a new and simple pathway for materials engineering with such segments.

The dynamic manipulation of the helicity in a cholesteric helical superstructure could enable precise control over its physical and chemical properties, thus opening numerous possibilities for exploring multifunctional *** cholesteric material satisfies the sufficiently small bending elastic effect, an electrically induced deformation named the cholesteric heliconical superstructure is formed. Through theoretical and numerical analysis, we systematically studied the tunable helicity of the heliconical superstructure, including the evolution of the corresponding oblique angle and pitch length. To further confirm the optical properties, Berreman’s 4 × 4 matrix method was employed to numerically analyze the corresponding structure reflection under the dual stimuli of chirality and electric field.

A novel luminescence boron compound, [2-(4, 5- diphenyl-1-imidazole-2-yl) pyridine] (DPIP-BPh2), has been synthesized by the reaction of pyridine-imidazole- based ligand. The decomposed temperature of DPIP-BPh2 is high than 200°C by thermogravimetric analyzer (TGA). For the three-layer organic light-emitting diodes (OLED) with the structure ITO/NPB/DPIP-BPh2/Alq3/Mg-Ag, an emission band centering at 490 nm with the maximum brightness of 1300 cd/m2 was observed, indicating a perfect blue OLED (CIE= 0.22, 0.36). DPIP-BPh2 forms a new family of organometallic emitting materials which which may bring benefits to people in practical applications. © 2020 IEEE.

The simulation of chemical reactions and mechanical properties including failure from atoms to the micrometer scale remains a longstanding challenge in chemistry and materials science. Bottlenecks include computational feasibility, reliability, and cost. We introduce a method for reactive molecular dynamics simulations using a clean replacement of non-reactive classical harmonic bond potentials with reactive, energy-conserving Morse potentials, called the Reactive INTERFACE Force Field (IFF-R). IFF-R is compatible with force fields for organic and inorganic compounds such as IFF, CHARMM, PCFF, OPLS-AA, and AMBER. Bond dissociation is enabled by three interpretable Morse parameters per bond type and zero energy upon disconnect. Use cases for bond breaking in molecules, failure of polymers, carbon nanostructures, proteins, composite materials, and metals are shown. The simulation of bond forming reactions was included via template-based methods. IFF-R maintains the accuracy of the corresponding nonreactive force fields and is about 30 times faster than prior reactive simulation methods. © 2021, CC BY-NC-ND.

Anode-free lithium (Li) metal batteries are desirable candidates in pursuit of high-energy-density batteries. However, their poor cycling performances originated from the unsatisfactory reversibility of Li plating/stripping remains a grand challenge. Here we show a facile and scalable approach to produce high-performing anode-free Li metal batteries using a bioinspired and ultrathin (250 nm) interphase layer comprised of triethylamine germanate. The derived tertiary amine and Li x Ge alloy showed enhanced adsorption energy that significantly promoted Li-ion adsorption, nucleation and deposition, contributing to a reversible expansion/shrinkage process upon Li plating/stripping. Impressive Li plating/stripping Coulombic efficiencies (CEs) of ≈99.3 % were achieved for 250 cycles in Li/Cu cells. In addition, the anode-free LiFePO 4 full batteries demonstrated maximal energy and power densities of 527 Wh kg −1 and 1554 W kg −1 , respectively, and remarkable cycling stability (over 250 cycles with an average CE of 99.4 %) at a practical areal capacity of ≈3 mAh cm −2 , the highest among state-of-the-art anode-free LiFePO 4 batteries. Our ultrathin and respirable interphase layer presents a promising way to fully unlock large-scale production of anode-free batteries.

As water pollution becomes increasingly serious, electrocatalytic hydrodechlorination (EHDC) technology has been widely used to remove chlorinated pollutants from waterbody. Due to the research studies on this topic are increasing and gradually maturing, a summary of the mechanism, influencing factors, and electrode optimization for EHDC is needed. This review provides an outline of the research status for EHDC technology in the removal of chlorinated organic compounds (COCs). The progress for reaction mechanisms and electrocatalysts is systematically summarized, and the main properties and important role of palladium (Pd) in the EHDC process are explored. Meanwhile, a detailed introduction to the optimization of Pd-based catalysts, especially the alloying of Pd with a second metal, layered construction of Pd-based catalysts and new reactor configurations in reactor design, is provided. The influencing factors, including pH, potential, coexisting ions, and catalyst loading in the EHDC reaction and their effects on the reaction, are also explored. Finally, the future development direction and challenges for EHDC are discussed. This review will enrich the theoretical studies in the field of EHDC and give new inspirations to researchers.
