【摘要】：金屬有機框架(MOFs)材料是一類新興的晶態(tài)材料,由金屬離子和有機配體構成,在分離、儲存氣體,多相催化,化學傳感,控制釋放及藥物傳遞等方面呈現(xiàn)出潛在的應用前景。特別是鑭系(4f)金屬有機框架材料,其具有強發(fā)射和獨特的光學性質。因此鑭系(4f)金屬有機框架材料在過去幾十年中被廣泛研究,應用在很多領域例如發(fā)光設備、生物醫(yī)學成像、熒光探針、熒光傳感器等。由于其可操作性、響應快速、高靈敏度、高選擇性,使鑭系(4f)金屬有機框架成功應用于熒光探針檢測化學物質。因環(huán)境污染及國土安全,硝基芳香爆炸物和重金屬離子備受關注。硝基苯是爆炸物的基本組成成分也是首要的環(huán)境污染物,引起了嚴重的健康問題。鐵是人體必須的元素,缺鐵可能會導致組織損傷或者引起心血管疾病。此外過量的鐵是高毒性的,使鐵元素成為首要的環(huán)境污染物。因此高靈敏度、高選擇性檢測硝基苯和Fe3+對人類健康、環(huán)境保護以及國土安全十分重要。近幾年,有機染料在工業(yè)生產中廣泛使用,并大量遺留在工業(yè)廢棄物、廢水中,對環(huán)境造成嚴重污染。因此,移除分離有機染料至關重要。本篇論文共分四章：引言章節(jié)包括金屬有機框架材料的簡介、剛性V-型羧酸配體和高度對稱性四齒羧酸配體構筑的金屬有機框架材料的應用,及本論文的選題意義和目前的研究進展。第一章介紹[2’,4’-二甲基]-1,1’：3’,1’-三聯(lián)苯-4,4”-二羧酸(H2mtpc)構筑的三種金屬有機框架(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屬于異質同晶,是具有聚輪烷構型、互穿插結構的3D金屬有機框架材料�；衔�1表現(xiàn)出極好的熒光性質。第二章描述了由高度對稱性四齒羧酸配體3,3’,5,5’-雙苯基四羧酸(H4bptc)、[1,1’：4’,1”-三聯(lián)苯]-3,3”,5,5”-四羧酸(H4tptc)與In(Ⅲ)在溶劑熱條件下構筑的兩種高孔隙率的金屬有機框架材料,[Me2NH2][In(bptc)](DMF)(CH3CN)(H2O)4 (4)、[Me2NH2][In(tptc)](DMF)2(H2O)4(5)。化合物5展現(xiàn)出良好的選擇性吸附分離有機染料的性能。結論章節(jié)總結了本論文中成功合成的五種MOFs材料的結構特征,并研究了MOFs材料在熒光傳感及有機染料吸附分離方面的性質,該工作為日后合成具有潛在應用價值的多功能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. Compound 1 exhibits excellent fluorescence properties.
