求助翻译： 葫环联脲是第四代超分子化合物，近年来因其在分子识别、分子组装、分子催化、污水处理、环境监测等多种领域有着广泛的应用潜力而受到了广泛的关注，成为研究的新热点。本文合成了几种葫环联脲并选取其中有一定水溶性的葫环联[7]脲作为研究的对象，以荧光光谱滴定法为主要手段，研究了其对三聚氰胺、邻苯二胺、9，10-二氨基苯基蒽的分子识别作用。本文的研究内容进一步拓宽了葫环联脲的分子识别范围，发展了基于超分子包合的测定毒物的新方法、新技术，开辟了葫环联脲应用的新方向。 全文共分五章： 第一章 对葫芦脲的起源、合成及性质特征做了简要的概括，然后对葫环联脲在分子识别等领域的研究进展做了介绍；同时结合本实验室前期工作的经验，提出了本论文的研究设想。 第二章 根据参考文献制备了葫环联[5,6,7]脲，并对其进行了1HNMR和红外光谱表征。 第三章 详细研究了CB[7]对有毒物质三聚氰胺的包合作用。计算了主客体的包结稳定常数并对包结机理等做了一些基本的探讨，利用分子模拟的手段推断了可能的包结模式。发展了利用水溶性葫芦脲进行食品分析的新手段，开辟了食品分析的新途径。 第四章 研究了CB[7]对有毒的环境污染物邻苯二胺的包合行为。计算了主客体的包结稳定常数并对包结机理等做了一些基本的探讨；同时研究了表面活性剂对CB[7]包合作用的影响，开辟了CB[7]在环境监测中的新的发展领域。 第五章 建立了一种基于超分子体系，用CB[7]测定染料小分子衍生物9，10-二氨基苯基蒽，研究了二者之间的包合作用，并求得了包结稳定常数。 |

Cucurbituril is the fourth generation of supramolecular compounds.It received extensive attention because of its wide range of potential applications in molecular recognition,molecular assembly,molecular catalysis,sewage treatment,environmental monitoring and so on,and it becomes a new hot research to be the future.We synthesized several Cucurbituril in this topic and we also chose the Cucurbituril with certain water-soluble between them as the object of the study.We take the Fluorescence Spectrometric Method as the major means.and we also do some research on it about molecular recognition to Melamine,O-phenylenediamine and 9 10-diaminodiphenyl Anthracene.Furthermore,the content we study in this topic broadens Cucurbituril's range of molecular recognition, developes a new method or a new technique to measure toxicant which is based on supramolecular,and opens up a new direction in Cucurbituril's application. The text is divided into five chapters: the first chapter It summarizes the origin,the synthesis and the characteristics of Cucurbituril in brief.Then introduces its research progress in the field of molecular recognition and so on.In the mean time,we roughed out some ideas for the research in this topic,combined with the experience of the preliminary work in our laboratory the second chapter We prepared Cucurbituril according to the reference and made 1HNMR and infra-red spectral characterize the third chapter We particularly study CB's clathration to the toxic,the Melamine, calculate host-guest's stability constant and basicly do some discussion about inclusion mechanism .Molecular simulation methods are used to inference possible inclusion models,water soluble Cucurbituril as a new method is developed for food analysis,and opened up new ways of food analysis. the forth chapter We particularly study CB's clathration to the toxic environmental pollutants, O-phenylenediamine. We calculate host-guest's stability constant and basicly do some discussion about inclusion mechanism . we also study surfactant's effect to CB's clathration at the same time ,which opens up a new field of development in environmental monitoring. the fifth chapter It establishes a method using CB to determine dyestuff's small molecules' derivatives: 9，10-diaminodiphenyl Anthracene, studies the clathration between them.We finally obtain the stability constant. |

Cucurbituril is among the 4th generation molecular compounds, and of great concerns due to its application potential in such fields as molecular recognition, assembling, catalysis, sewage disposal and circumstantial monitoring. Several kinds of cucurbituril were synthesized in our study, and some of them, which were well-watersoluble, were investigated on their molecular recognition effect of trimeric cyanamide, o-diaminobenzene and 9,10-diaminophenyl anthracene by fluorescence titration. The range of cucurbituril molecular recognition was further broadened and toxicant determination was developed based on supramolecular inclusion-complexes, which was a new orientation of cucurbituril. 先翻译第一段 |
