Problems solved by technology

However, the solubility of polyaniline itself is poor, only soluble in very strong polar N -methyl-pyrrolidone, and the solvent is very expensive
In addition, the fluorescence performance of polyaniline itself is also poor.

Abstract

The invention discloses an aminocarbazole/aniline copolymer and a synthesis method thereof. The synthesis method comprises the following steps: dissolving 3-amino-9-ethylcarbazole and aniline in different mol ratios in a first solvent to form a comonomer solution; dissolving a certain amount of oxidant in a second solvent to form an oxidant solution; and after blending the oxidant solution and the comonomer solution, shaking intensely for some time, standing, and reacting completely to obtain the aminocarbazole/aniline copolymer. The invention has the advantages of simple synthesis steps, high efficiency and high controllability; and the obtained carbazole/aniline conducting polymer can be used in the fields of electrodes, electron screening, electrostatic prevention, electrochromic materials, fluoroscopic examination and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of novel organic conjugated polymers, in particular to an aminocarbazole / benzene [0002] Amine copolymers and methods for their synthesis. Background technique [0003] As a new type of functional material, organic conjugated polymers have not only the electronic properties of metals and semiconductors, but also the mechanical properties of easy processing and flexibility of polymers. The quasi-one-dimensional macromolecular structure of organic conjugated polymers endows them with unique optical, electrical, and magnetic properties, so it has become a hot spot in applied research in recent years. [0004] Polyaniline has become one of the most widely studied organic conjugated polymers because of its cheap, easy synthesis, high conductivity, good environmental stability, and specific acid-doping / base-dedoping effects.
