Embodiment 1

[0058] Add 417 mg (2 mmol) of FA monomer into 15 mL of n-hexane solvent, and then ultrasonically disperse it for 5-10 min to promote the complete dissolution of FA monomer to prepare a monomer solution. Dissolve 2270.8mg (14mmol) of anhydrous ferric trichloride in 10mL of nitromethane solvent, and then ultrasonically disperse it for 10-15min to promote the complete dissolution of ferric oxide to prepare an oxidizing agent solution. After the two solutions were kept at 70° C. for 30 minutes, the monomer solution was added dropwise to the above-mentioned oxidant solution which was continuously stirred. The reaction was continued for 24 h in a 70 °C water bath. The liquid surface of the solution was stratified, changing from reddish brown to black, and black precipitate was formed. After the reaction, the solution was suction-filtered, and then the product was washed with absolute ethanol several times to remove residual monomers and oligomers, and then the obtained product was ...

Abstract

The invention discloses a method for preparing polyfluoranthene in a biphasic system, which is characterized in that: fluoranthene is dissolved into a first solvent to prepare a fluoranthene solution, oxidant is dissolved into a second solvent to prepare an oxidant solution, and the first solvent and the second solvent are not mixed; and the fluoranthene solution is dripped into the oxidant solution to completely react to produce the polyfluoranthene. The method has simple, convenient and easy operation, needs simple equipment, and has adjustable and high-efficient reaction conditions.

Description

technical field [0001] The invention relates to a method for preparing polyfluoranthene in a two-phase system. Background technique [0002] Fluoranthene is a highly arylated four-ring condensed ring aromatic hydrocarbon containing only two elements of carbon and hydrogen. It consists of two single bonds connecting a benzene ring and a naphthalene ring at the same time: [0003] [0004] Structural formula 1 Schematic diagram of the structure of fluoranthene monomer (FA) [0005] Fluoranthene has singular fluorescence properties, and its fluorescence lifetime and fluorescence quantum yield are longer and larger than theoretically calculated values ​​(Bark KM, Force R K. Fluorescence properties of fluoranthene as a function of temperature and environment[J].Spectrochimica acta.A , 1993, 49(11): 1605-1611). Due to the strong fluorescence emission characteristics of fluoranthene, the fluorescence detector (FD) has extremely high sensitivity and selectivity to this type of ...
