Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

Abstract Perovskite light‐emitting diodes (PeLEDs) has emerged as one of the most promising technologies for next generation lighting and high‐definition display applications due to their exceptional color purity, tunable emission, low material costs. In past eleven years, PeLEDs have made remarkable progress researchers come up with many innovative approaches. Among them, additive engineering based on small organic molecules (SOMs) been demonstrated effective strategies enhance external quantum efficiency (EQE) stability PeLEDs. Notably, champion EQEs red, green, blue devices cannot be realized without participation SOMs. Here, this paper first reviews development PeLEDs, followed by a focused discussion specific application mechanism SOMs in Lastly, it analyzes challenges provides an outlook future development.

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 1, 2025

This study reports the synthesis and characterization of a novel CsCu2I3@UiO-66(Ce)-NH2 hybrid material through state-of-the-art in-situ growth lead-free non-toxic CsCu2I3 perovskite within porous UiO-66(Ce)-NH2. The composite exhibits high surface area with nanostructures uniformly dispersed UiO-66(Ce)-NH2 framework. host-guest was considered as an effective stable catalyst for one-pot three-component copper(I)-catalyzed intermolecular alkyne-azide cycloaddition (CuAAC) or click reaction. Under optimized conditions, utilizing water at room temperature, nominal exhibited superior activity, outperforming its individual components. Remarkably, demonstrated good recyclability reusability over several catalytic runs. Mechanistic studies unveiled synergistic cooperation between MOF, leading to enhanced performance improved stability perovskite. developed multifunctional solid offers potential applications in catalysis related fields, paving way innovative sustainable organic beyond.

Harnessing Transfer Deep Learning Framework for the Investigation of Transition Metal Perovskite Oxides with Advanced p-n Transformation Sensing Performance

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

Gas sensing materials based on transition metal perovskite oxides (TMPOs) have garnered extensive attention across various fields such as air quality control, environmental monitoring, healthcare, and national defense security. To overcome challenges encountered in traditional research, a deep learning framework combining natural language processing technology (Word2Vec) crystal graph convolutional neural network (CGCNN) was adopted this study, proposing predictive method that incorporates comprehensive data set consisting of 1.2 million literature abstracts 110,000 structure entries. This assessed the optimal combination zinc-cobalt bimetallic ions complexed with ligands precursors for oxides. The regulatory function ligand concentration p-n transformation oxide performance identified, optimization strategies were provided. Zn(II)/Co(III)/1-methyl-1H-imidazole-2-carboxylic acid complex synthesized demonstrated exceptional sensitivity selectivity toward volatile organic compounds (VOCs), particularly 3-hydroxy-2-butanone (3H-2B). mechanism deeply analyzed through construction hyper-synergistic interaction matrix model n-type sensors (HSLIM-n) parametrized surface-ligand resonance p-type (PSLRM-p), enhancing fundamental understanding material properties. Even highly interfering environments, functionalized exhibited outstanding 3H-2B gas, low detection limit 25 parts per billion (ppb). research approach has facilitated transfer learning-enhanced framework, which shown high efficiency predicting precise design oxides, its effectiveness meticulously verified detailed experimental validation.
