【摘要】:金屬有機(jī)框架(MOFs)材料是一類(lèi)新興的晶態(tài)材料,由金屬離子和有機(jī)配體構(gòu)成,在分離、儲(chǔ)存氣體,多相催化,化學(xué)傳感,控制釋放及藥物傳遞等方面呈現(xiàn)出潛在的應(yīng)用前景。特別是鑭系(4f)金屬有機(jī)框架材料,其具有強(qiáng)發(fā)射和獨(dú)特的光學(xué)性質(zhì)。因此鑭系(4f)金屬有機(jī)框架材料在過(guò)去幾十年中被廣泛研究,應(yīng)用在很多領(lǐng)域例如發(fā)光設(shè)備、生物醫(yī)學(xué)成像、熒光探針、熒光傳感器等。由于其可操作性、響應(yīng)快速、高靈敏度、高選擇性,使鑭系(4f)金屬有機(jī)框架成功應(yīng)用于熒光探針檢測(cè)化學(xué)物質(zhì)。因環(huán)境污染及國(guó)土安全,硝基芳香爆炸物和重金屬離子備受關(guān)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(yán)重的健康問(wèn)題。鐵是人體必須的元素,缺鐵可能會(huì)導(dǎo)致組織損傷或者引起心血管疾病。此外過(guò)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(cè)硝基苯和Fe3+對(duì)人類(lèi)健康、環(huán)境保護(hù)以及國(guó)土安全十分重要。近幾年,有機(jī)染料在工業(yè)生產(chǎn)中廣泛使用,并大量遺留在工業(yè)廢棄物、廢水中,對(duì)環(huán)境造成嚴(yán)重污染。因此,移除分離有機(jī)染料至關(guān)重要。本篇論文共分四章:引言章節(jié)包括金屬有機(jī)框架材料的簡(jiǎn)介、剛性V-型羧酸配體和高度對(duì)稱(chēng)性四齒羧酸配體構(gòu)筑的金屬有機(jī)框架材料的應(yīng)用,及本論文的選題意義和目前的研究進(jìn)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(gòu)筑的三種金屬有機(jī)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(zhì)同晶,是具有聚輪烷構(gòu)型、互穿插結(jié)構(gòu)的3D金屬有機(jī)框架材料;衔1表現(xiàn)出極好的熒光性質(zhì)。第二章描述了由高度對(duì)稱(chēng)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(gòu)筑的兩種高孔隙率的金屬有機(jī)框架材料,[Me2NH2][In(bptc)](DMF)(CH3CN)(H2O)4 (4)、[Me2NH2][In(tptc)](DMF)2(H2O)4(5);衔5展現(xiàn)出良好的選擇性吸附分離有機(jī)染料的性能。結(jié)論章節(jié)總結(jié)了本論文中成功合成的五種MOFs材料的結(jié)構(gòu)特征,并研究了MOFs材料在熒光傳感及有機(jī)染料吸附分離方面的性質(zhì),該工作為日后合成具有潛在應(yīng)用價(jià)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. Chapter 2 describes the highly symmetric tetradentate carboxylic acid ligands 3PTECARBOXIC acid (H4bptc), [1 1 1: 4 BX 1 "-TIBYL] -3", Two kinds of metal-organic frame materials with high porosity, [Me2NH2] [In (bptc)] (DMF) (CH3CN) (H2O) 4 (4), constructed by H4tptc and In (鈪,
