摘要: 开发新型有机/配合物长余辉材料，并通过研究其结构与性质的关系，来提高长余辉性能，是当前的研究热点。本实验涉及一种铜碘簇配位聚合物(CuIU)，其存在立方(C，Cubic)和三方(T，Trigonal)相。虽然二者的分子式相同，但由于结构框架的结晶方式不同，导致较刚性的T-CuIU具有明显的长余辉性质，而柔性的C-CuIU则没有。合成过程在盐溶液中常温进行，条件温和，仅需简单的搅拌、离心、干燥等操作就能完成，适合在本科生实验中推行。其中，短时间搅拌反应得到的是C-CuIU，而长时间搅拌得到的是T-CuIU。C、T两相的转化容易控制，二者的余辉差别肉眼可观察。通过引入结构模型教具、荧光墨水、丝网印刷等可进一步提高课程的生动性与趣味性。该实验有助于学生了解金属簇配合物的合成方法，认识配合物结构与性质之间的深刻联系。同时，实验还融合了X射线粉末衍射仪、荧光仪、热重分析仪等科研仪器的操作，具有较好的科教融合效果。

Abstract: To develop new long afterglow luminescent materials based on organics or coordination compounds, and improve the long afterglow performance through studying the relationship between the molecular structures and properties becomes one of the hot research topics currently. This experiment is mainly related to the Cu(I)-iodide cluster-based coordination polymer (CuIU). There are two phases for CuIU, C-CuIU and T-CuIU crystallized in the cubic and trigonal space groups, respectively. Though the molecular formulas of C- and T-CuIU are same, T-CuIU displays much better long afterglow property than C-CuIU. The synthesis of CuIU is performed in NaI aqueous solution at room temperature under gentle environment. The whole experiment is carried out through easy stirring, centrifugation and drying operations, which is appropriate for undergraduate laboratory teaching. The product obtained by short stirring time is verified as C-CuIU, while that with long stirring time is verified as T-CuIU. The transformation between C and T is easily controlled and they display notably different lifetimes. The plastic models of these two structures, preparation of luminescent ink and silk-screen printing are also introduced in teaching to further improve the vividness and interest of the course. This experiment is helpful for students to understand the synthesis method of metal cluster compounds and the deep relation between structures and properties in coordination compounds. Meanwhile, the experiment involves the operations of X-ray powder diffractometer, spectrofluorometer and thermal gravimetric analyzer, which promote the science and education integration in the teaching process.
