The invention relates to a method for preparing a polymer, disclosing a chemical oxidation method of a polypyrene. The method comprises the following steps: dissolving pyrene monomer in normal hexane to obtain the organic solution of the pyrene monomer and dissolving oxidant in nitromethane to obtain the organic solution of the oxidant; dropping the organic solution of the pyrene monomer into theorganic solution of the oxidant and stirring; after the dropping, carrying out thermostatic reaction within a temperature range of 20-70 DEG C; and obtaining the polypyrene after separation, impurityremoval and drying. The method for synthesizing the polypyrene has the advantages of easy operation, mild synthesis condition, relatively high yield, small energy consumption, easy popularization andmass production. Besides, the method more effectively avoids such defect that the yield of the polymer obtained by the electric polymerization method is limited by the electrode area.
Description
Chemical Oxidative Synthesis of Polypyrene technical field The invention relates to a preparation method of a polymer, in particular to a preparation method of polypyrene. Background technique Polycyclic aromatic hydrocarbons are a class of compounds connected by two or more benzene rings sharing two adjacent carbon atoms, which are widely used in dyes, resins, drugs and other fields. Most fused-ring aromatics have strong fluorescence. Pyrene, as a typical aromatic compound with four benzene rings condensed, has unique fluorescence properties. Fluorescent probes for nucleic acids, carbohydrates, etc., used for various fluorescent assays (G. Jones, VI. Vullev. Contribution of apyrene fluorescence probe to the aggregation propensity of polypeptides. Org. Lett. 2001, 3: 2457-2460). Polymers synthesized from fused aromatic hydrocarbon pyrene monomers have a larger range of conjugated π bonds in the long chain range, and the chain rigidity and planarity of the monomer units th...
