【摘要】：金属有机框架(MOFs)材料是一类新兴的晶态材料,由金属离子和有机配体构成,在分离、储存气体,多相催化,化学传感,控制释放及药物传递等方面呈现出潜在的应用前景。特别是镧系(4f)金属有机框架材料,其具有强发射和独特的光学性质。因此镧系(4f)金属有机框架材料在过去几十年中被广泛研究,应用在很多领域例如发光设备、生物医学成像、荧光探针、荧光传感器等。由于其可操作性、响应快速、高灵敏度、高选择性,使镧系(4f)金属有机框架成功应用于荧光探针检测化学物质。因环境污染及国土安全,硝基芳香爆炸物和重金属离子备受关注。硝基苯是爆炸物的基本组成成分也是首要的环境污染物,引起了严重的健康问题。铁是人体必须的元素,缺铁可能会导致组织损伤或者引起心血管疾病。此外过量的铁是高毒性的,使铁元素成为首要的环境污染物。因此高灵敏度、高选择性检测硝基苯和Fe3+对人类健康、环境保护以及国土安全十分重要。近几年,有机染料在工业生产中广泛使用,并大量遗留在工业废弃物、废水中,对环境造成严重污染。因此,移除分离有机染料至关重要。本篇论文共分四章：引言章节包括金属有机框架材料的简介、刚性V-型羧酸配体和高度对称性四齿羧酸配体构筑的金属有机框架材料的应用,及本论文的选题意义和目前的研究进展。第一章介绍[2’,4’-二甲基]-1,1’：3’,1’-三联苯-4,4”-二羧酸(H2mtpc)构筑的三种金属有机框架(MOFs)材料[Tb(mtpc)1.5(DMA)(H2O)]·2H2O (1), [Dy(mtpc)1.5(DMA)(H2O)]·2H2O (2)和[Er(mtpc)1.5(DMA)(H2O)]·2H2O (3)。化合物1、2、3属于异质同晶,是具有聚轮烷构型、互穿插结构的3D金属有机框架材料。化合物1表现出极好的荧光性质。第二章描述了由高度对称性四齿羧酸配体3,3’,5,5’-双苯基四羧酸(H4bptc)、[1,1’：4’,1”-三联苯]-3,3”,5,5”-四羧酸(H4tptc)与In(Ⅲ)在溶剂热条件下构筑的两种高孔隙率的金属有机框架材料,[Me2NH2][In(bptc)](DMF)(CH3CN)(H2O)4 (4)、[Me2NH2][In(tptc)](DMF)2(H2O)4(5)。化合物5展现出良好的选择性吸附分离有机染料的性能。结论章节总结了本论文中成功合成的五种MOFs材料的结构特征,并研究了MOFs材料在荧光传感及有机染料吸附分离方面的性质,该工作为日后合成具有潜在应用价值的多功能MOFs材料提供了新的思路和方法。
[Abstract]:Organometallic frame (MOFs) is a kind of new crystalline materials, which is composed of metal ions and organic ligands. It has potential applications in separation, gas storage, heterogeneous catalysis, chemical sensing, controlled release and drug delivery. In particular, lanthanide (4f) metal-organic frame materials have strong emission and unique optical properties. Therefore, lanthanide (4f) metal-organic frame materials have been widely studied in recent decades, and have been widely used in many fields such as luminescent devices, biomedical imaging, fluorescent probes, fluorescence sensors and so on. Because of its maneuverability, rapid response, high sensitivity and high selectivity, the lanthanide (4f) metal-organic framework has been successfully applied to the detection of chemical substances with fluorescent probes. Because of environmental pollution and homeland security, nitroaromatic explosives and heavy metal ions have attracted much attention. Nitrobenzene is the basic component of explosives and the primary environmental pollutant, causing serious health problems. Iron is a necessary element in the body. Iron deficiency can lead to tissue damage or cardiovascular disease. In addition, excess iron is highly toxic, making iron the primary environmental pollutant. Therefore, the detection of nitrobenzene and Fe3 with high sensitivity and selectivity is very important for human health, environmental protection and homeland security. In recent years, organic dyes are widely used in industrial production, and a large number of industrial wastes and wastewater, causing serious environmental pollution. Therefore, it is very important to remove and separate organic dyes. This paper is divided into four chapters: the introduction includes the introduction of organometallic framework materials, the application of rigid V-type carboxylic acid ligands and highly symmetrical tetradentate carboxylic acid ligands. And the significance of this paper and the current research progress. Chapter 1 introduces three organometallic frame (MOFs) materials [Tb (mtpc) 1.5 (DMA) (H2O)] 2H2O (1) constructed by [Tb (mtpc) 1. 5 (DMA) (H 2O] -1: 1: 1: 1: 1: 3, 1: 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 4 "- dicarboxylic acid (H2mtpc), 3 kinds of organometallic frame materials, [Tb (mtpc). 5 (DMA) (H2O]. [Dy (mtpc) 1.5 (DMA) (H _ 2O] 2H2O (2) and [Er (mtpc) 1.5 (DMA) (H _ 2O] 2H2O (3). Compound 1: 2, which belongs to heterogeneous isomorphism, is a 3D organometallic frame material with poly-rotane configuration and interpenetrating structure.
