摘要:阴离子在自然界和生物体内广泛存在，在许多生物和化学过程中都起着基础而重要的作用。但是阴离子的过量存在又会对环境造成污染、对生命体造成危害。CN对环境、人体健康存在巨大的潜在威胁，CN一旦进入人体，对人有致命的危险。目前对CN识别检测的方法中，荧光探针因其识别快速、灵敏度高、选择性好而被广泛研究。探针与CN的识别作用机理主要分为C-C键的形成、质子转移、C-B键的形成、电子转移等。本课题在已有文献的基础上，设计了基于C-C键形成的荧光探针。该荧光探针以1,8-萘酰亚胺为荧光发色团，以苯乙炔为连接体，以醛基为结合CN的接受体。因所设计化合物的分子内的电子排布以及结构特性，在与CN作用后，其光谱数据会发生显著变化，进而达到识别检测CN的目的。31493

Naphthalimide fluorescent receptors based o-n remote control of hydrogen bond: Design, synthesis and anion recognition
Abstract: Anion exists widely in nature and organism, which play an important role in many biological and chemical processes. However, the excess anions can pollute the environment and do harm to the living organisms. CN, one of the anions, is a huge potential threat to the environment and human health. Once CN enters the human body, it can be fatal for human life. Among the current recognition and detection method of CN, the fluorescent probe has been extensively studied because of its advantages of fast recognition, high sensitivity and high selectivity. Recognition mechanism of the probe to CN are mainly pided into the formation of C-C bond, the transformation of the proton, the formation of C-B bond, the transformation of the electron and so on. Based on the previous document, we design a fluorescent probe, which is based on the formation of C-C bond by remote control of intramolecular hydrogen bond. The fluorescent probe based on 1,8-naphthalimide derivatives, using the benzene acetylene as the connector, and aldehyde group as a binding site to recognize CN. According to the configuration of the electron and the structural characteristics of the molecular compounds, after the probe binding with CN, its spectrum data has remarkable changes, and be achieved to the purpose of identifying and detecting CN.
