Embodiment 1

[0036] Example 1 A method for preparing a conductive polymer (P1) based on benzothiadiazole

[0037] The conductive polymer (P1) based on benzothiadiazole is as follows:

[0038]

[0039] The preparation method of P1 specifically comprises the following steps:

[0040] (1) Synthesis of monomer A: The synthesis of monomer A is carried out according to the following reaction equations.

[0041]

[0042] 1) 100mL toluene (Toluene) as a solvent, 3-methoxythiophene (4.5674g, 40mmol) and triethylene glycol monomethyl ether (19.704g, 120mmol) as raw materials added to the reaction bottle, and then add p-toluenesulfonamide (PTSA, 0.689g, 4mmol) as a catalyst, react at 100 °C for 20h. After the reaction was completed, the solvent was removed by reduced pressure distillation to obtain the crude product, and the crude product was purified through the silica gel column to obtain the target product A1, a total of 4.927g (yield 50%);

[0043] 2) In the nitrogen state, add magnetons and 3.203g...

Abstract

The invention belongs to the technical field of organic semiconductor materials, and particularly relates to a conductive polymer and a synthesis method and application thereof.The main chain structure of the conductive polymer is formed by polymerizing benzodiazole or benzotriazole serving as a basic repetitive unit and an Ar repetitive unit; the chemical stability and chemical modification property of repetitive units such as benzodiazole or benzotriazole are strong, so that the introduction of substituent groups or side chains is facilitated. Besides, by introducing an alkyl chain or an ethylene glycol side chain to thiophene connected with repetitive units such as benzodiazole or benzotriazole, the solubility of polymer molecules can be improved, and the obtained polymer can be dissolved in common solvents such as dichloromethane, chloroform and methylbenzene. The conductive polymer disclosed by the invention has the characteristics of definite structure, simplicity in synthesis and the like, can be applied to an organic semiconductor layer of an organic electrochemical transistor as a channel active material, and has good performance.

Description

Technical field [0001] The present invention belongs to the field of organic semiconductor material technology, specifically relates to a conductive polymer and synthesis methods and applications thereof. Background [0002] Bioorganic electronics can solve many problems in biomedical diagnosis and treatment, such as it can detect low concentrations of bioanalytes, weak bioelectric signals and some pathogens, which is extremely versatile. Among them, the most representative bio-organic electrochemical material is the organic electrochemical transistor (OECTS). OECTS is highly sensitive, requires only a small voltage to work, the preparation process is very simple, in addition to its good compatibility with organisms, it can respond quickly. These features make OECTS widely used to detect the biological signals of neurons, detect a variety of analytes, etc., while good biocompatibility makes it possible to make wearable devices. [0003] OECT is mainly composed of five parts: sour...
