摘要:阴离子在环境科学、医学及生命科学领域扮演着极其重要的角色,因而设计和发展新颖阴离子受体是超分子化学研究的热点。较之传统的基于N-H键对X-的键合作用的阴离子受体、N-H键与C-H键协同识别X-的阴离子受体,反应型荧光探针具有高度专一选择性与非常高的灵敏性而备受青睐,对于反应型荧光探针的研究主要集中在F-切断Si-O/Si-C键达到识别的目的。近年来,含C-H键的受体,特别是带吸电子基的C-H键因其表现出强于传统的N-H键对X-的相互作用也成为目前研究的热点,本课题拟在此基础上设计一种新颖1,8-萘酰亚胺衍生物作为荧光探针,通过研究分析其新颖1,8-萘酰亚胺衍生物的光谱,找到最佳的实验结果,为后续较深入的研究工作提供理论基础。 毕业论文关键词: 阴离子识别;氢键;萘酐;荧光探针;光谱研究
Spectroscopic study of a novel 1, 8-naphthalimide derivatives
Abstract:The design and development of artificial anion receptors have attracted great attention in supramolecular chemistry because of anions play in a wide variety of biological, clinical and environmental sciences. Compared with the traditional hydrogen-bonding interaction (N-H…X-) and the combination of N-H and C-H bond, reaction-based fluorescent probe shows high selectivity and high sensitivity. Recently, the popular strategy for design of fluoride chemosensor are mainly concentrated on F- -induced Si-O/Si-C bond cleavage to achieve the specific output signals. In recent years, receptor containing C-H bond, especially those with electron-withdrawing C-H bond shows more stronger binding with anions than the traditional N-H bond, which has attractive much attention. In this thesis, a novel 1,8-naphthalimide derivatives was designed and synthesized in a facile method, and the spectroscopic analysis including UV-vis and Fluorescence was investigated intensively. All the experimental data was collected and optimized for the manuscript preparation.
