【摘要】：多氮唑類有機配體構(gòu)筑的過渡金屬配合物具有多種新穎的結(jié)構(gòu)和功能性質(zhì),在光、磁、含能功能材料和環(huán)境應(yīng)用領(lǐng)域展示出廣泛的應(yīng)用前景。本文合成了一系列具有不同形貌和結(jié)構(gòu)特征的配合物,研究了全部化合物的結(jié)構(gòu)和功能性質(zhì)。全文共分為三章:第一章為前言,主要介紹了四唑、三唑及其衍生物構(gòu)筑的配合物的研究進展以及四唑衍生物作為高氮含能材料包括納米含能材料的合成方法與應(yīng)用的研究現(xiàn)狀。第二章介紹了以5,5'-偶氮四唑(AZT2-)為配體與過渡金屬Cr(Ⅲ)鹽構(gòu)筑三種配合物[Cr(H_2O)_6]_2(AZT)_3·6H_2O(1),[Cr(OH)(AZT)(H_2O)_3]·2H_2O(2)和[Cr(OH)(H_2O)_5]AZT·H_2O(3)的納米晶體的合成、結(jié)構(gòu)表征與性質(zhì)。使用原位合成法實現(xiàn)了從一種納米晶體到另一種納米晶體的轉(zhuǎn)換。通過紅外光譜、拉曼光譜、元素分析、光電子能譜(XPS)、熱重(TG)和差熱分析(DSC)、掃描電鏡(SEM)和透射電鏡(TEM)等表征了這些含能納米晶體的形貌結(jié)構(gòu)特征和光譜性質(zhì)以及形貌相關(guān)的熱穩(wěn)定性。同時表征了這些納米晶體的撞擊、摩擦、火焰和電火花感度性質(zhì)并進行了比較分析。通過對這些納米晶體的高溫(500℃以上)的熱分解產(chǎn)物的組成和結(jié)構(gòu)分析,確定其分解產(chǎn)物為Cr(III)金屬氧化物,這為過渡金屬氧化物的納米晶體的合成提供了一種新的方法。第三章介紹了以4-(1H-1,2,4-三唑-1-甲基)苯甲酸[H(4-tzbc)]為配體與兩種過渡金屬鹽CoCl_2·6H_2O和CuCl_2·4H_2O構(gòu)筑了{[Co(4-tzbc)2(H_2O)_2]×2H_2O}_n(4和[Cu(4-tzbc)_2]_n(5)兩種配合物。以4-偶氮四唑苯酚(H_2atp)為配體與過渡金屬MnCl_2·6H_2O鹽構(gòu)筑了{[Mn(Hatp)_2(H_2O)_4]×3H_2O}(6)和{[Mn_2(atp)_2(H_2O)_6]}(7)兩種配合物。培養(yǎng)了四種配合物4-7的單晶并用X-射線單晶衍射技術(shù)表征了它們的晶體結(jié)構(gòu)。分析結(jié)果表明配合物4和5為一維鏈結(jié)構(gòu),6為單核結(jié)構(gòu),7為雙核結(jié)構(gòu)。此外還表征了配合物4和5的熒光性質(zhì),發(fā)現(xiàn)他們的固體能發(fā)出綠色熒光。此外還表征了配合物7的磁學(xué)性質(zhì)。
[Abstract]:The transition metal complexes constructed by polyazolium organic ligands have a variety of novel structure and functional properties. They are widely used in the fields of light, magnetism, energetic functional materials and environmental applications. In this paper, a series of complexes with different morphologies and structural characteristics have been synthesized, and the structure and functional properties of all compounds have been studied. This paper is divided into three chapters: the first chapter is the preface, which mainly introduces tetrazole, The research progress of the complexes constructed by triazole and its derivatives and the research status of synthesis methods and applications of tetrazole derivatives as high-nitrogen energetic materials including nano-energetic materials. In chapter 2, three complexes [Cr (H _ 2O) _ 6] _ 2 (AZT) _ 3 6H_2O (1) were constructed by using AZT2- as ligand and transition metal Cr (鈪，
