Novel function diamine monomer containing carbazole and large conjugated structure and preparation method and application thereof

The invention discloses a novel function diamine monomer containing carbazole and a large conjugated structure and a preparation method and application thereof. The novel function diamine monomer is started from a basic monomer element and obtained through a series of chemical reaction of helogenation reaction, Wittig-Horner reaction, UIImann reaction, Suzuki reaction and the like. A synthetic method of the novel function diamine monomer is simple in process, easy to purify and suitable for industrial production. The monomer has a large non-planar large conjugated structure, has the effect of aggregation-induced emission, and can be used for synthetizing high-performance functionalized polymers of polyamide, polyimide, polyamide-imide, polyester-imide and the like.
