Abstract

The invention discloses a fluorine-containing functional diamine monomer with a large conjugated structure as well as a synthesis method and an application thereof. The synthesis method comprises the following steps of: firstly allowing di-halogenated fluorine to react with halogenated nitrobenzene, linking halogen atoms with other chemical groups to form a large conjugated system, and finally reducing binitro into diamine; or firstly carrying out a chemical coupling reaction between two active hydrogen atoms in fluorine to form the large conjugated structure, carrying out a Suzuki reaction on the large conjugated structure and two halogen atoms to obtain the diamine, and finally obtaining the novel fluorine-containing functional diamine monomer. By means of the specific structure of the diamine monomer, the polymer obtained by the diamine monomer has the advantage of good solubility, and the diamine monomer and the polymer can also achieve certain photoelectric properties; and the synthesis method has the advantages of simple process and easy purification procedure, thus being applicable to industrial production. The fluorine-containing functional diamine monomer has obvious characteristics of luminescence aggregation and induction, thus the diamine monomer can be used for synthesizing high-performance functional polymers such as polyamide, polyimide, polyamideimide, polyesterimide and the like.

[0002] Polyimide is one of the best heat-resistant varieties among engineering plastics that have been industrialized at present. It has outstanding properties unmatched by other materials, such as high mechanical strength, good high and low temperature resistance, excellent dielectric properties, and film-forming properties. OK wait. Since the development and industrialization of DuPont in the United States in the 1960s, it has been applied in various fields, especially in aerospace, aviation, microelectronics and military fields. Since polyimide is generally insoluble in organic sol...
