【摘要】：近年来含氮类杂环有机化合物因其自身具有的高内吸性、易修饰性以及对人体的低毒性等优点,在医药、农药方面得到了广泛的应用。本文主要就N-甲基-N,N'-二(吡啶-2-甲基)乙二胺,以及4-(二(1-吡唑)甲基)吡啶的系列合成工艺进行优化,探究温度、时间以及反应物物质的量比对反应的影响,最终得到两种杂环化合物最优的制备工艺。具有自旋交叉性质的配合物,在作为新一代分子开关以及信息原件的开发方面有较大研究意义。在对化合物进行工艺优化后,用化合物与Fe2+进行自组装,获得一系列新的磁性材料,针对这些材料进行结构的表征以及磁性质的研究。本论文主要由五个章节构成。第一章为绪论,介绍了课题的研究背景。第二章为含氮杂环有机化合物的制备过程,介绍了系列吡啶化合物的制备流程,以及对化合物进行表征。第三章为本文的重点,对系列吡叮化合物的制备工艺进行研究,把控各因素对反应产生的影响,确认最佳制备条件。第四章以一个吡啶化合物为中心对其进行系列配合物的构建,并对系列配合物进行结构的鉴定以及性质的分析。第五章为结论与展望。
[Abstract]:In recent years, nitrogen-containing heterocyclic organic compounds have been widely used in medicine and pesticides because of their high internal absorption, easy modification and low toxicity to human body. In this paper, a series of synthetic processes of N- methyl-N- (pyridine-2-methyl) -ethylenediamine and 4- (bis (1-pyrazole) methyl) pyridine were optimized to explore the effects of temperature, time and the ratio of reactants to the amount of reactants on the reaction. Finally, the optimal preparation process of two heterocyclic compounds was obtained. The complexes with spin-cross properties have great significance in the development of new generation molecular switches and information originals. A series of new magnetic materials were obtained by self-assembly of the compounds with Fe2 after the optimization of the process. The structure and magnetic properties of these materials were characterized and studied. This thesis consists of five chapters. The first chapter is the introduction, which introduces the research background of the subject. In chapter 2, the preparation process of nitrogen-containing heterocyclic organic compounds is introduced. The preparation process and characterization of pyridine compounds are introduced. The third chapter is the focus of this paper, the preparation process of a series of pyridine compounds is studied, and the optimum preparation conditions are confirmed by controlling the influence of various factors on the reaction. In chapter 4, a series of complexes were constructed with a pyridine compound as the center, and the structures and properties of the complexes were analyzed. The fifth chapter is the conclusion and prospect.
