Article Abstract
Defect is one of the key factors limiting optoelectronic performances of organic-inorganic hybrid systems. Although high-efficiency bidentate ligands based electroluminescent (EL) clusters reported, until present, only few EL clusters based on monodentate ligands are realized since their structural instability induces more surface/interface defects. Herein, this bottleneck is first overcome in virtue of interfacial passivation by electron transporting layers (ETL). Through using TmPyPB with meta-linked pyridines as ETL, photoluminescent (PL) and EL quantum efficiencies of the simplest monophosphine Cu I cube [TPP] Cu I are greatly improved by ≈2 and 23 folds, respectively, as well as ≈200 folds increased luminance, corresponding to a huge leap from nearly unlighted (<20 nits) to highly bright (>3000 nits). The passivation effect of TmPyPB on surface defects of cluster layer is embodied as preventing interfacial charge trapping and suppressing exciton nonradiation.

Anode-free sulfide-based all-solid-state lithium metal batteries (ASSLMBs), which eliminate the need for a lithium metal anode during fabrication, offer superior energy density, enhanced safety, and simplified manufacturing. Their performance is largely influenced by the interfacial properties of the current collectors. Although previous studies have investigated the degradation of sulfide electrolytes on commonly used copper (Cu) and stainless steel (SS) current collectors, the impact of spontaneously formed surface oxides, such as copper oxide (CuO/CuO) and chromium oxide (CrO), on interfacial stability remains underexplored.

High-nickel layered oxide LiNiCoMnO (NCM, ≥ 0.8) materials are considered optimal cathodes for lithium-ion power batteries owing to their high energy density, commendable cycling performance, and cost-effectiveness. However, structural collapse and interface instability during cycling result in diminished cycling stability, significantly hindering their commercial viability.

We used a hybrid two-step perovskite deposition method that is compatible with industry-standard textured silicon, incorporating a perovskite surface treatment based on 1,3-diaminopropane dihydroiodide. The interaction of this molecule with the perovskite surface increased the majority charge carrier concentration at the electron-selective contact, which reduced interfacial recombination.

Rational design of both mechanistic pathways and material compositions is essential to advance COF-based electrochemiluminescence (ECL) systems. In this study, aggregation-induced emission covalent organic framework (AIE-COF) nanoprobes with excellent ECL performance were developed based on Tb-functionalized covalent organic framework (Tb@A-COF). The Tb@A-COF system demonstrates enhanced ECL performance through synergistic integration of three complementary mechanisms: (1) (4',4',4',4'-(1,2-ethenediylidene)tetrakis [1,1'-biphenyl]-4-carboxaldehyde (ETBC) ligands function as antenna-like sensitizers that amplify luminescence intensity by 14.

Metal halide perovskite solar cells (PSCs) hold promise for next-generation photovoltaics but are restricted by suboptimal efficiency and poor long-term stability. In inverted PSC architectures, self-assembled monolayers (SAMs) are widely employed as hole-selective layers (HSLs) due to their favorable energy-level alignment and negligible parasitic absorption. However, traditional SAMs often exhibit weak intermolecular interactions, leading to film aggregation, poor interfacial contact, and severe nonradiative recombination.
