Abstract

Abstract Knowledge about the mechanisms involved in the structural development of solid materials at the atomic level is essential for designing rational synthesis protocols for these compounds, which may be used to improve desired technical properties, such as light emission, conductivity, magnetism, porosity or particle size, and may allow the tailored design of solid materials to generate the aforementioned properties. Recent technological advancements have allowed the combination of synchrotron-based in situ X-ray diffraction (XRD) with in situ optical spectroscopy techniques, providing researchers with remarkable opportunities to directly investigate structural changes during synthesis reactions. Among the various available methods to measure optical properties, in situ luminescence, UV/Vis absorption, and light transmission spectroscopies are highlighted here, with in situ luminescence being subdivided into in situ luminescence analysis of coordination sensors (ILACS) and time-resolved laser fluorescence spectroscopy (TRLFS). This article consists of a review of 122 references exploring various aspects of in situ analyses, with particular emphasis on the use of XRD-combined techniques in the study of metal-ligand exchange processes during the formation, phase transitions and decomposition of solid materials, including complexes, coordination polymers, metal-organic frameworks, nanoparticles and polyoxo- or chalcogenide metallates. We will then conclude with an exploration of future trends in this exciting research field.
利用光谱学和x射线衍射分析原位监测金属配体交换过程:综述
在原子水平上了解固体材料结构发展的机制对于设计这些化合物的合理合成方案至关重要,这些方案可用于改善所需的技术性能,如发光、电导率、磁性、孔隙率或粒径,并可能允许定制固体材料的设计以产生上述性能。最近的技术进步使得基于同步加速器的原位x射线衍射(XRD)和原位光学光谱技术相结合,为研究人员提供了直接研究合成反应过程中结构变化的绝佳机会。在各种可用的测量光学性质的方法中,重点介绍了原位发光、紫外/可见吸收和光透射光谱,其中原位发光又细分为配位传感器原位发光分析(ILACS)和时间分辨激光荧光光谱(TRLFS)。本文综述了122篇文献,探讨了原位分析的各个方面,特别强调了在固体材料形成、相变和分解过程中使用xrd结合技术研究金属配体交换过程,包括配合物、配位聚合物、金属有机框架、纳米颗粒和多氧或硫族金属化物。最后,我们将探讨这个令人兴奋的研究领域的未来趋势。
