Paragraph 0039; 0040; 0041, (2018/03/09)
The invention discloses a synthetic method of a V-type rigid-flexible molecule based on pyrene and multi-branch polyethylene glycol chains, and the structural general formula of the compound is as shown in the specification. The preparation method comprises the following specific steps: refluxing a compound having the structure formula as show in the specification, another compound having the structure formula as show in the specification and anhydrous sodium carbonate in a solvent to react to obtain a compound having the structure formula as show in the specification, refluxing the compound in the presence of potassium hydroxide, adding concentrated hydrochloric acid for acidification, so as to obtain a compound having the structure formula as show in the specification; dissolving the obtained compound and dimethylformamide in a solvent, allowing the compound to react with thionyl chloride to obtain a compound having the structure formula as show in the specification, refluxing the obtained compound and 4-hydroxyl-4'-iodo-biphenyl to react, carrying out a sonogashira reaction on the obtained compound and a compound having the structure formula as show in the specification, so as to obtain the V-type rigid-flexible molecule based on pyrene and multi-branch polyethylene glycol chains. The method has the advantages of being reasonable in synthesis process and high in yield, the product has stronger fluorescence in an organic solvent and can be used as a fluorescent dye or a fluorescent molecular probe; and has good self-assembly performance in an aqueous solution; the structured aggregate can be used as a nano reactor or a drug carrier.
