Abstract ：
Lanthanide ion contained metal-organic frameworks (MOFs) have garnered significant attention in the fields of solid-state lighting and chemical sensing due to their porous structure and distinctive optical properties. However, they also present challenges because of the limited photoluminescence (PL) intensity resulting from the parity-forbidden f-f transitions of lanthanide ions. Herein, the study reports a new heterometallic MOFs Ln3Li2L4 (Li-Ln-MOF, Ln = Y, Eu, Tb and Dy, L = deprotonated 1,3,5-tris(4-carboxyphenyl)benzene) with a Brunauer-Emmett-Teller (BET) surface area of 774.1 m2/g. The porous crystal structure of Li-Ln-MOF is characterized by three kinds of channels interpenetrating with each other. By employing ligand alternation and lanthanide ion alloying strategies, Li-Y1-xEux-MOF1 crystal isostructural with Li-Ln-MOF is synthesized by using 2,4,6-tris(4-carboxyphenyl)-1,3,5-triazine (H3TATB) as ligand. The Li-Y0.7Eu0.3-MOF1 crystal excels in the comprehensive performance with a BET surface area of 858.8 m2 g-1 and a near-unity PL quantum yield. The time density functional theory and natural transition orbitals calculations unravel that the outstanding optical properties Li-Y0.7Eu0.3-MOF1 originates from the charge transfer between TATB3- and Eu3+. Benefiting from the excellent comprehensive performance of Li-Y1-xEux-MOF1, the study reveals their potentials as single-composition white-light emission and fluorescent sensing probe for the detection of nitrobenzene. A strategy via ligand alteration is developed to achieve a near-unity photoluminescence quantum yield in lanthanide metal-organic frameworks (Ln-MOFs) with a porosity of up to 53.6%. Mechanistic investigation through theoretical calculation and time-resolved spectra unravel that Ln-MOF displayed outstanding optical properties ascribed to the charge transfer from the triple excited state of ligand to the Ln3+. image

Abstract ：
The serious dendrite formation and safety hazards associated with side reactions hinder the practical application of lithium metal batteries. A molecular customization strategy based on both physical and chemical properties is reported. A copolymer of acrylamide and hexafluorobutyl acrylate molecules is used as an artificial solid electrolyte interface(ASEI) for lithium metal to achieve dynamic interface protection during cycling. The amide group serves as the rigid unit, while the hexafluorobutyl group serves as the flexible unit, and imparts excellent mechanical properties to the copolymer. Synergistically abundant CF bonds exhibit excellent water and oxygen resistance and have good electrolyte affinity. The ester and amide groups serve as amphiphilic sites for Li+ and PF6-, regulating the ion flux at the interface and achieving dendrite-free lithium deposition. During cycling, the organic-inorganic composite SEI dynamically evolves to safeguard the lithium metal, preventing undue electrolyte consumption. The copolymer achieves stable cycling for 1500 and 950 h at 1 and 2 mA cm-2, respectively. It demonstrates excellent performance with LiNi0.8Co0.1Mn0.1O2 and LiFePO4 cathodes. This study introduces a new approach to designing polymers at the molecular level to optimize the physical properties/chemical activity of lithium metal interfaces. The serious dendrite formation and safety hazards associated with side reactions hinder the practical application of lithium metal batteries. A molecular customization polymer based on physicochemical properties as ASEI is reported. The copolymer has excellent mechanical properties and water and oxygen resistance. The ester and amide groups serve as amphiphilic sites, regulating the ion flux and achieving dendrite-free lithium deposition. image

Abstract ：
Side reactions and dendrite growth triggered by the unstable interface and inhomogeneous deposition have become the biggest obstacle to the commercialization for lithium metal batteries. In this study, a highly-chlorinated organic-inorganic hybrid interfacial protective layer is developed by rationally tuning the interfacial passivation and robustness to achieve the convenient and efficient Li metal anode. The polyvinyl chloride (PVC) can effectively resist water and oxygen, which is confirmed by density functional theory. The organic-dominant solid electrolyte interphases (SEI) with lithium chloride are investigated by the X-ray photoelectron spectroscopy (XPS) with little mineralization of oxide, such as Li2 O and Li2 CO3 . With such artificial SEI, a uniform and dense lithium deposition morphology are formed and an ultra-long stable cycle of over 500 h are achieved even at an ultra-high current density of 10 mA/cm2 . Moreover, the simple and convenient protected anode also exhibits excellent battery stability when paired with the LiNi0.8 Co0.1 Mn0.1 O2 (NCM811) and LiFePO4 (LFP) cathode, showing great potential for the commercial application of lithium metal batteries.

Abstract ：
Doping is a recognized method for enhancing catalytic performance. The introduction of strains is a common consequence of doping, although it is often overlooked. Differentiating the impact of doping and strain on catalytic performance poses a significant challenge. In this study, Cu-doped Bi catalysts with substantial tensile strain are synthesized. The synergistic effects of doping and strain in bismuth result in a remarkable CO2RR performance. Under optimized conditions, Cu-1/6-Bi demonstrates exceptional formate Faradaic efficiency (>95%) and maintains over 90% across a wide potential window of 900 mV. Furthermore, it delivers an industrial-relevant partial current density of -317 mA cm(-2) at -1.2 V-RHE in a flow cell, while maintaining its selectivity. Additionally, it exhibits exceptional long-term stability, surpassing 120 h at -200 mA cm(-2). Through experimental and theoretical mechanistic investigations, it has been determined that the introduction of tensile strain facilitates the adsorption of *CO2, thereby enhancing the reaction kinetics. Moreover, the presence of Cu dopants and tensile strain further diminishes the energy barrier for the formation of *OCHO intermediate. This study not only offers valuable insights for the development of effective catalysts for CO2RR through doping, but also establishes correlations between doping, lattice strains, and catalytic properties of bismuth catalysts.

Abstract ：
Modulating the morphology of metal-organic frameworks (MOFs) has been identified as an effective strategy for enhancing the electrocatalytic performance of CO2 reduction reactions (CO2RR). In this study, CAU-17 MOFs ([Bi (BTC)(H2O)]& sdot;2 H2O & sdot;MeOH) were prepared via a sonication-assisted method at room temperature, which is considered a simpler technique compared to the conventional hydrothermal method. Additionally, the morphology of CAU-17 MOFs was further regulated by incorporating a rare-earth metal (La), resulting in the observation of two distinct structures, i.e. CAU-17 hexagonal prism (CAU-17-HP) and CAU-17 layer (CAU-17Layer). Compared to CAU-17-HP, CAU-17-Layer exhibits an excellent selectivity towards formate with the maximum Faradaic efficiency of 95.5% at1.1 VRHE in an H-cell. Subsequently, the limited catalytic activity of CAU-17-Layer was boosted by anchoring nano CeO2 onto its surfaces (CeO2 @CAU-17-Layer). The as-prepared composite catalyst demonstrated outstanding performance in the conversion of CO2 to formate, with a current density surpassing - 100 mA cm -2 at potentials more negative than - 1.0 VRHE and reaching - 200 mA cm -2 at1.5 VRHE in a flow cell. This study demonstrates the significant potential of morphology-engineered and rareearth metals composited MOFs in facilitating highly efficient reduction of CO2.

Abstract ：
Covalent organic frameworks (COFs) with excellent structural tunability have emerged as fascinating photocatalysts to fulfill future energy demands. Here, we developed a COFs heterostructure by assembling two COFs for photocatalytic overall water splitting. The resulting heterostructure exhibited an effective spatial separation of photoredox sites originating from the efficient separation of photoinduced charge carriers through an orientated interfacial electron transfer pathway. Accordingly, the heterostructure of the COFs displays excellent activity for stoichiometric water splitting into H-2 and O-2 under 5 W white LED light irradiation. Our efficiencies of H-2 and O-2 evolution rates up to 120 and 58 mu mol g(-1) h(-1) are significantly higher than those reported previously. The combination of experiments and theoretical calculations shows that water oxidation proceeds by a metal-free hydration-mediated pathway. This work sheds light on a rational design of the COF heterostructure with spatially separated photoredox for water splitting.

Abstract ：
Conjugated polymers with strong absorption in the second near-infrared (NIR-II) window have multiple applications. However, the development of new type of NIR-II conjugated polymers via facile and green methods remains challenging. Herein, this work reports a mild and convenient transition-metal-free method to synthesize near-infrared absorbing quinoidal conjugated polymers containing para-azaquinodimethane (AQM) moieties. The AQM quinoidal conjugated polymers with unique molecular structures and tunable optoelectronic properties can be synthesized by combining the Knoevenagel polycondensation of aromatic dialdehyde monomers with commercially available 1,4-diacetyl-2,5-piperazinedione and the following alkylation reaction. The resultant polymer PQ-DPP shows remarkable NIR-II absorption with a narrow band gap of about 1.08 eV. PQ-DPP nanoparticles exhibit high photothermal conversion efficiency of up to 48% under 1064 nm laser irradiation (1 W cm(-2)) endowing this polymer with potential in bio-related applications.
