Paragraph 0109-0111; 0115, (2021/05/12)
The invention relates to the technical field of organic photoelectric polymers, and particularly relates to a fluorene-containing diamine monomer, a polyimide film and a preparation method and application thereof. The fluorene-containing diamine monomer provided by the invention has a structure as shown in a formula I defined in the description. The fluorene-containing diamine monomer provided by the invention is polymerized with a dianhydride monomer, so that the heat resistance of a polyimide film can be greatly improved, and the thermal expansion coefficient of the film can be reduced.
