摘要

本文报告了一种新型碘化铜杂化化合物 (DABCO-H)CuKI3，它具有包晶结构。包括单晶 X 射线衍射、X 射线光电子能谱（XPS）和光致发光研究在内的表征技术阐明了该化合物的结构和发光特性。密度泛函理论（DFT）计算和 XPS 价带分析证明，该化合物具有蓝色磷光，归因于金属到配体和卤化物到配体的混合电荷转移跃迁。此外，(DABCO-H)CuKI3 对亚甲基蓝染料具有显著的吸附能力。动力学模型显示，薄膜和颗粒内扩散过程都对吸附速率有贡献。

Bridging two worlds: (DABCO-H)CuKI3 a hybrid copper iodide phosphor with a perovskite structure

A novel copper iodide hybrid compound, (DABCO-H)CuKI3, featuring a perovskite structure is here reported. Characterization techniques, including single crystal X-ray diffraction, X-ray photoelectron spectroscopy (XPS), and photoluminescence studies, elucidate the structural and luminescent properties. The compound exhibits blue phosphorescence, attributed to mixed metal-to-ligand and halide-to-ligand charge transfer transitions, as supported by density functional theory (DFT) calculations and XPS valence band analysis. Furthermore, (DABCO-H)CuKI3 displays a remarkable adsorption capacity towards methylene blue dye. Kinetic modelling reveals that both film and intra-particle diffusion processes contribute to the adsorption rate.

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
