Incorporating a functional unit into the multidimensional coordination polymer skeleton is an efficient way to improve the stability of materials and expand their application. In this paper, anionic copper iodide inorganic functional modules are incorporated into one-dimensional extended chains by using a unique bidentate cationic organic ligand. Benefiting from the ionic extended structure, the resulting hybrid possesses a remarkable stability with a decomposition temperature as high as 300 °C. Meanwhile, the hybrid material exhibits intrinsic greenish white-light emission with a high photoluminescent quantum yield of 70%. The emission was investigated by temperature-dependent emission spectra, which proved to be the result of the synergistic effect of two energy states. The novel synthetic strategy provides an efficient route for the development of functional organic metal halides.
将功能单元引入多维配位聚合物骨架是提高材料稳定性并拓展其应用的有效方法。本文通过使用独特的双齿阳离子有机配体，将阴离子碘化铜无机功能模块引入一维延伸链中。得益于离子延伸结构，所得杂化物具有高达300℃的分解温度，稳定性显著。同时，该杂化材料呈现出本征的绿白色发光，光致发光量子产率高达70%。通过变温发射光谱对其发射进行了研究，结果表明这是两种能态协同作用的结果。这种新颖的合成策略为功能性有机金属卤化物的开发提供了一条有效途径。
