【摘要】：從發(fā)現(xiàn)第一代主體分子——冠醚,到現(xiàn)在,短短幾十年里,超分子化學(xué)得到快速的發(fā)展和壯大,研究以非共價鍵作用力為核心的主客體化學(xué),其不論是在理論研究還是在實際應(yīng)用方面都有舉足輕重的地位。近些年,帶電荷的大環(huán)化合物主體分子相繼被報道,這些帶電荷的主體分子不僅有著鮮明的結(jié)構(gòu)特征,而且性能上有著顯著且突出的功能,帶正電荷的主體分子可以包結(jié)中性和帶負(fù)電荷的客體分子,帶負(fù)電荷的主體分子可以包結(jié)中性和帶正電荷的客體分子,同時帶電荷的主體分子在離子對識別,光電材料,軟材料和分子機(jī)器等方面都有十分突出的作用。本論文主要有兩部分,第一部分主要研究以三鍵和氮雜苯拓展的聯(lián)吡啶正電荷環(huán)番,第二部分主要探討用磺酸根和羧酸根衍生化的負(fù)電荷冠醚,負(fù)電荷個數(shù)可以通過pH調(diào)控。第一部分,引入了幾種新的結(jié)構(gòu)來擴(kuò)展對聯(lián)吡啶結(jié)構(gòu),并利用聯(lián)吡啶去合成對應(yīng)的四正電荷環(huán)番,已經(jīng)初步合成了對苯二乙炔擴(kuò)展的對聯(lián)吡啶環(huán)番,發(fā)現(xiàn)其對二萘并-38-冠-10有較弱的鍵合作用;接著我們以吡嗪苯拓展的聯(lián)吡啶作為缺電子部件高產(chǎn)率合成了正電荷環(huán)番,并研究其對含有2到7個苯環(huán)的多環(huán)芳烴客體分子的鍵合作用,并在此基礎(chǔ)上高產(chǎn)率合成了[2]輪烷。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,這種衍生化的水溶冠醚帶有四個負(fù)電荷,當(dāng)在不同pH條件下,羧酸根可以在羧酸和羧酸根之間轉(zhuǎn)化,與此同時主體對陽離子客體的鍵合強(qiáng)度也隨之改變。
[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.
