Synthesis And Properties Of Perylene Derivative Fluorescence Switches With Synergistic Interaction

Perylene derivitives are important chromospheres in dye chemistry. In light oftheir diverse and fascinating properties, such as excellent electron acceptor ability,high molar extinction coefficient in the visible region, and high fluorescence quantumyields. Perylene derivitives represent a classical example of an inherently robust andoutstandingly versatile family of organic compounds that have been extensivelyutilized for a wide range of high technology applications. The purpose of this paper isto design and synthesize a series of different structural types of fluorescent molecularprobes based on perylene derivatives. By the interaction with a variety of metal ions,the corresponding UV-visible absorption and fluorescence spectra was Determined，in order to research collaborative recognition between the molecular probe and Metalions. This Paper includes the following:Chapter1: Mechanism and application of fluorescent molecular probes wassummarized; The research progress on perylene compounds and stable nitroxideradicals were described in detail; Research topic of this thesis was Proposed.Chapter2: The nitration reaction of several perylene derivatives were studied.3,4:9,10-perylene tetracarboxylic dianhydride andtetrabutyl-perylene-3,4,9,10-tetracarbonylate were successfully nitrified. In addition,The nitration reaction of diphenol-substituted perylene diimide was made apreliminary study.Chapter3: A series of fluorescence probes based on perylene derivatives withpyridyl or quinolyl group as recognition group have been designed and synthesized.By determining the corresponding UV-visible absorption and fluorescence spectra,the research on collaborative recognition between recognition group and metal ionswas performed.Chapter4: A series of fluorescent molecular switches based on perylenederivatives with pyridyl group and nitroxide radical group have been designed andsynthesized. Determining the corresponding UV-visible absorption and fluorescencespectra, in order to research collaborative recognition of nitroxide radical group and pyridyl group for metal ions.
