【摘要】：金屬-有機(jī)凝膠(Metal-Organic Gel, MOG)是指金屬原子和有機(jī)配體通過(guò)配位作用形成的具有三維網(wǎng)絡(luò)結(jié)構(gòu)的半固體狀物質(zhì),同時(shí)在凝膠中還存在一些非共價(jià)鍵的相互作用,例如氫鍵,范德華力,π-π：堆積等。與金屬-有機(jī)框架(Metal-Organic Framework, MOF)相比,金屬有機(jī)凝膠的結(jié)晶性較差,而且結(jié)構(gòu)不明確,但是它仍然存在MOF沒(méi)有的一些優(yōu)點(diǎn),例如：(1)得到金屬有機(jī)凝膠的反應(yīng)溫度較低,甚至有一部分凝膠在室溫下就能生成；(2)反應(yīng)時(shí)間短,反應(yīng)所需要的溶劑量少；(3)反應(yīng)溶劑廉價(jià)易得,大多數(shù)的反應(yīng)都是以乙醇,水,N,N.-二甲基甲酰胺(DMF)或者他們的混合物為溶劑,毒性�。�(4)可以利用不同形狀的反應(yīng)容器得到不同形狀的凝膠,這使得它在工業(yè)上和商業(yè)上有更加廣泛的用途。同時(shí),配體和金屬離子的相互作用,多齒有機(jī)配體的定向作用都使得金屬有機(jī)凝膠在催化、傳感、陰陽(yáng)離子識(shí)別、熒光、氣體吸附與分離、電化學(xué)等方面有著潛在的應(yīng)用價(jià)值。本文主要合成了三種亞氨基二乙酸(Iminodiacetic Acid, IDA)衍生物的配體,分別用三種配體與Cr3+, Al3+, Fe3+, Zr4+反應(yīng)得到五組不同的具有三維網(wǎng)絡(luò)結(jié)構(gòu)的金屬有機(jī)凝膠,測(cè)定了它們的多孔性質(zhì),并探討了它們?cè)跉怏w吸附方面的應(yīng)用。1、利用半剛性配體BP-IDA,分別與Cr(Ⅲ)鹽,Al(Ⅲ)鹽進(jìn)行溶劑熱反應(yīng),得到了兩種新穎的金屬有機(jī)凝膠。通過(guò)流變、掃描電子顯微鏡、粉末X射線衍射、紅外光譜、X射線光電子能譜、氮?dú)馕摳降葴y(cè)試對(duì)凝膠材料的結(jié)構(gòu)和物理性質(zhì)進(jìn)行了詳細(xì)研究。2、利用半剛性配體BP-IDA與Fe(Ⅲ)鹽在室溫下反應(yīng),得到了一種新穎的金屬有機(jī)凝膠。這種Fe凝膠在一定條件下可以進(jìn)行溶膠一凝膠的相互轉(zhuǎn)換,將該凝膠材料高溫活化,活化后的多孔碳材料具備潛在的電化學(xué)性能。通過(guò)流變、掃描電子顯微鏡、粉末X射線衍射、紅外光譜、氮?dú)馕摳降葴y(cè)試對(duì)材料的結(jié)構(gòu)和物理性質(zhì)進(jìn)行了詳細(xì)研究。3、利用半剛性配體TPB-IDA和TPM-IDA分別與Zr(Ⅳ)鹽進(jìn)行溶劑熱反應(yīng),得到了兩種新穎的金屬有機(jī)凝膠。通過(guò)流變、掃描電子顯微鏡、粉末X射線衍射、紅外光譜、X射線光電子能譜、氮?dú)馕摳降葴y(cè)試對(duì)凝膠材料的結(jié)構(gòu)和物理性質(zhì)進(jìn)行了詳細(xì)研究。
[Abstract]:Metal-Organic Gel (MOG) is a semisolid substance with three-dimensional network structure formed by the coordination of metal atoms and organic ligands. At the same time, there are some non-covalent bond interactions in the gel, such as hydrogen bond, van der Waals force. 蟺-蟺: stacking. Compared with Metal-Organic Framework (MOFF), organometallic gels have poor crystallinity and unclear structure. However, there are still some advantages that MOF does not have. For example, the reaction temperature of organometallic gels is relatively low, and even some of them can be formed at room temperature. (2) the reaction time is short and the amount of solvent needed for the reaction is less; The reaction solvent is cheap and easily available, and most of the reactions are in the solvent of ethanol, water, N-dimethylformamide (DMF) or their mixture, with little toxicity; Different shapes of gels can be obtained by using different shapes of reaction vessels, which makes them more widely used for industrial and commercial applications. At the same time, ligands interact with metal ions. The orientation of polydentate organic ligands makes organometallic gels in catalysis, sensing, anion recognition, fluorescence, gas adsorption and separation. In this paper, three ligands of iminodiacetic acid (IDA) derivatives were synthesized. Five different groups of organometallic gels with three-dimensional network structure were obtained by the reaction of three ligands with Cr3, Al3, Fe3 and Zr4, and their porous properties were measured. Their application in gas adsorption was also discussed. The semi-rigid ligand BP-IDA was used for solvothermal reaction with Cr (鈪，
