Abstract

The invention belongs to the crossing field of organic photochemistry, organic fluorine chemistry and medicinal surfactant chemistry, and particularly relates to a nitrogen-containing heterocyclic fluorocarbon surfactant synthesized by adopting a photoreaction-click reaction method and preparation of a water-phase micelle of the nitrogen-containing heterocyclic fluorocarbon surfactant. An intermediate 1-N-(3-azidopropyl)-3-methyl-3-perfluorooctyl-5-methoxyl-indolone is synthesized by adopting a photoreaction, photochemical intramolecular ring-closure reaction is carried out by using ultraviolet-visible light irradiation, and under the catalysis of copper sulfate / sodium ascorbate, the intermediate and monopropynyl-monomethyl-polyethylene glycol are subjected to a click reaction, and the nitrogen heterocyclic ring fluorocarbon surfactant is prepared. The green synthesis method is simple and easy to implement, low-toxicity, efficient and commercialized green chemical reagents are used in the synthesis process, and the synthesis method is atom-economical. The preparation method passes a small-amount synthesis test in a laboratory and is successful. Then, water-phase micelles of the nitrogen-containing heterocyclic fluorocarbon surfactant are prepared and are characterized.

Description

Technical field [0001] The present invention belongs to organic photochemical, organoic fluorochemistry, and pharmaceutically acceptable chemical crossains, and more particularly Preparation. Background technique [0002] The present invention is intended to illustrate the contents of the present invention, and should not be understood that the applicant is clearly considered or estimated by the applicant to express the application for the present invention, the applicant is approved. The prior art of the day. [0003] The fluorocarbon surfactant is replaced by a fluorine atom, i.e., a fluorocarbon chain, is replaced by a fluorine atom. Strong bonding capacity of fluorine atom and carbon atom (4.86 × 10 5 J / mol) is given to the fluorocarbon surfactant with a variety of special properties, the shield of the fluorine atoms increases the stability of the fluorocarbon type surfactant to make it chemically resistant to chemical properties and thermal stability. The surface tension o...
