摘　　要：介绍一个综合化学实验——长磷光寿命主客体材料合成实验。本实验首先利用硝酸锌、间苯二甲酸、2-甲基咪唑在水溶液中混合,快速制备配合物单晶;然后利用单晶X-射线衍射、粉末X-射线衍射、稳态瞬态荧光光谱仪等技术对其进行表征。可以利用该方法将染料(罗丹明B、香豆素、曙红Y、4-[4-(二甲氨基)苯乙烯基]-1-甲基吡啶碘等)分子包覆到配合物基质中,探究不同客体对材料性质的影响。通过该实验的设计和实施,使学生在掌握基本实验操作技能的同时,能够结合所学基础化学理论知识,利用现代仪器,不仅可以提高学生的科学思维和综合运用知识的能力,还可以提高学生解决问题的能力和创新意识。This paper introduces a comprehensive chemical experiment-host-guest material synthesis experiment with long phosphorescence life.In this experiment,zinc nitrate,m-phthalic acid and 2-methyl imidazole were mixed in an aqueous solution to quickly prepare the complex single crystal.The crystal structure was characterized by single crystal X-ray diffraction and powder X-ray diffraction,and its phosphorescence properties were studied by steady-state transient fluorescence spectrometer.Based on this method,the dyes (Rhodamine B,Coumarin,Eosin Y,4-[4-(dimethylamino) styrene]-1-methylpyridine iodine,etc.) can be encapsulated into the complex matrix.The effects of different guests on the luminescence properties of the materials can be explored.The experimental research methods are varied,which can enable students to flexibly apply the existing basic chemical theoretical knowledge and modern instruments means,which is beneficial to cultivate students’ active thinking and practical ability.
