【摘要】：从发现第一代主体分子——冠醚,到现在,短短几十年里,超分子化学得到快速的发展和壮大,研究以非共价键作用力为核心的主客体化学,其不论是在理论研究还是在实际应用方面都有举足轻重的地位。近些年,带电荷的大环化合物主体分子相继被报道,这些带电荷的主体分子不仅有着鲜明的结构特征,而且性能上有着显著且突出的功能,带正电荷的主体分子可以包结中性和带负电荷的客体分子,带负电荷的主体分子可以包结中性和带正电荷的客体分子,同时带电荷的主体分子在离子对识别,光电材料,软材料和分子机器等方面都有十分突出的作用。本论文主要有两部分,第一部分主要研究以三键和氮杂苯拓展的联吡啶正电荷环番,第二部分主要探讨用磺酸根和羧酸根衍生化的负电荷冠醚,负电荷个数可以通过pH调控。第一部分,引入了几种新的结构来扩展对联吡啶结构,并利用联吡啶去合成对应的四正电荷环番,已经初步合成了对苯二乙炔扩展的对联吡啶环番,发现其对二萘并-38-冠-10有较弱的键合作用;接着我们以吡嗪苯拓展的联吡啶作为缺电子部件高产率合成了正电荷环番,并研究其对含有2到7个苯环的多环芳烃客体分子的键合作用,并在此基础上高产率合成了[2]轮烷。第二部分,合成了以磺酸根和羧酸根衍生化的水溶性冠醚36-冠-10,这种衍生化的水溶冠醚带有四个负电荷,当在不同pH条件下,羧酸根可以在羧酸和羧酸根之间转化,与此同时主体对阳离子客体的键合强度也随之改变。
[Abstract]:From the discovery of the first generation of the main molecule, crown ether, to the present, the supramolecular chemistry has developed and expanded rapidly in a few short decades. The study of the host and guest chemistry at the core of the non covalent bond force has been found in both theoretical and practical applications. In recent years, the large ring compound with charge is the main compound. One after another, the body molecules have been reported that these charged main molecules not only have distinct structural characteristics, but also have significant and prominent functions. The main molecules with positive charges can bind neutral and negatively charged guest molecules, and negatively charged main molecules can bind neutral and positively charged guest molecules and live on the charge. There are two main parts in this paper. The first part of this paper mainly deals with the positive charge ring of bipyridine with three bonds and nitrogen heterozygous benzene, and the second part mainly deals with the negative charge crown ethers derived from sulfonic roots and carboxylic acids. The number of charge can be regulated by pH. In part 1, several new structures have been introduced to expand the bipyridine structure and use bipyridine to synthesize the corresponding four positive charge ring, which has preliminarily synthesized the antipyridine cycle of benzyl two acetylene expansion, and found that it has a weaker bonding effect on two naphthalene and -38- crown -10; then we use pyrazine. Benzyl extended bipyridine syntheses the positive charge ring as the high yield of the electronic component, and studies its bonding effect on the guest molecules of polycyclic aromatic hydrocarbons containing 2 to 7 benzene rings. On this basis, the high yield rate syntheses [2] lorane. The second part syntheses the water-soluble crown ethers 36- crown -10 derived from sulfonic root and carboxylic acid root, this derivatization. The water soluble crown ethers have four negative charges, when under different pH conditions, the carboxylic acid roots can be converted between carboxylic acids and carboxyacid roots, while the bond strength of the main body changes with the cationic object.
