【摘要】：作為一種多孔材料,金屬-有機(jī)框架化合物在吸附、分離、傳感和催化等領(lǐng)域有著巨大的應(yīng)用潛力。本文中合成了一系列以羧酸為配位端基的開(kāi)鏈冠醚橋連配體、咔唑橋連配體和以嘧啶為端基芴橋連的有機(jī)配體。研究了它們與過(guò)渡金屬、主族金屬的組裝化學(xué),得到了16例結(jié)構(gòu)新穎的配位化合物,利用X-射線單晶衍射表征了它們的結(jié)構(gòu),對(duì)部分化合物的物理化學(xué)性質(zhì)進(jìn)行了探究。一、合成了以羧酸為配位端基的開(kāi)鏈冠醚橋聯(lián)柔性配體L1-L4,研究了其與過(guò)渡金屬的自組裝化學(xué),得到5例未見(jiàn)報(bào)道的配位化合物,通過(guò)X-射線單晶衍射表征了它們的結(jié)構(gòu)。發(fā)現(xiàn)一例Cu(II)為金屬中心的離散型分子籠。二、合成了以羧酸為配位端基的咔唑橋聯(lián)的剛性配體L5-L8,研究了它們與主族金屬、過(guò)渡金屬(M=Mg(II),Cd(II),Ni(II))的自組裝化學(xué),得到4例新的配位化合物,通過(guò)X-射線單晶衍射表征了它們的結(jié)構(gòu)。其中一例三維Cd(II)-MOF可在單晶狀態(tài)下吸附碘分子。三、通過(guò)對(duì)合成條件的調(diào)控研究得到三種大小形貌比較均勻的微米尺度的Cd(II)-MOF,利用五羰基鐵氣相氧化沉積的方法得到無(wú)定形Fe2O3@Cd-MOF、Fe3O4@Cd-MOF兩種鐵基納米復(fù)合材料,探究了其對(duì)催化羅丹明B降解反應(yīng)的催化性能。通過(guò)一鍋法組裝合成Cd S量子點(diǎn)@Cd-MOF復(fù)合材料,簡(jiǎn)單研究了其對(duì)光解水產(chǎn)氫實(shí)驗(yàn)的催化性能。四、合成了一系列以嘧啶為配位端基的芴橋連的有機(jī)配體L9-L13,與過(guò)渡金屬通過(guò)自組裝得到7例新的配位化合物,通過(guò)X-射線單晶衍射表征了它們的結(jié)構(gòu)。通過(guò)改變配體取代基、陰離子等條件可實(shí)現(xiàn)對(duì)化合物結(jié)構(gòu)的調(diào)控。
[Abstract]:As a porous material, metal - organic frame compounds have great potential for application in the fields of adsorption, separation, sensing and catalysis. In this paper, a series of ligands of open chain crown ether bridging ligands, carbazole bridging ligands and pyrimidine as the terminal fluorene bridge have been synthesized. The assembly chemistry of them with transition metals and host metals has been studied. 16 novel coordination compounds have been obtained. Their structures have been characterized by X- ray single crystal diffraction, and the physicochemical properties of some compounds have been explored. First, we synthesized the open chain crown ether bridged flexible ligand L1-L4 with carboxylic acid as the coordination end group. We studied its self assembly chemistry with transition metal, and obtained 5 unreported coordination compounds. Their structures were characterized by X- ray single crystal diffraction. A discrete molecular cage with Cu (II) as the metal center was found. Two, we synthesized the rigid ligand L5-L8 with carbazole bridged with carboxylic acid as the coordination end group. We studied their self-assembly chemistry with main group metals, transition metals (M=Mg (II), Cd (II), Ni (II)), and obtained 4 new coordination compounds. Their structures were characterized by X- ray single crystal diffraction. One of the three dimensional Cd (II) -MOF can adsorb iodine molecules in the state of a single crystal. Three, through the research on the regulation of synthesis conditions for uniform micron scale Cd three size morphology (II) -MOF, using the method of gas phase oxidation of iron pentacarbonyl deposited by amorphous Fe2O3@Cd-MOF, Fe3O4@Cd-MOF two kinds of Fe based nano composite material, explores its catalytic performance for the catalytic degradation of Luo Danming B. Cd S quantum dot @Cd-MOF composite was synthesized by one pot method, and its catalytic performance on the photodissociation of aquatic hydrogen was studied. Four, we synthesized a series of organic ligands L9-L13 with pyrimidine as the coordination terminal group, and obtained 7 new coordination compounds by self-assembly with transition metals. Their structures were characterized by X- ray single crystal diffraction. The structure of the compound can be regulated by changing the ligand substituents and anions.
