Embodiment 1 3

[0070] The preparation of embodiment 1 terpolymer:

[0071] (1) Preparation of monomer M1 (9,12-dibromo-7H-benzoimidazo(2,1-a)benzo(de)isoquinolin-7-one): in N 2 Under the atmosphere, add 1.8-naphthalene dicarboxylic anhydride and 3,6-dibromo-1,2-phenylenediamine at a molar ratio of 1:1, put 10 mL of glacial acetic acid in a three-necked flask, stir and heat up to the reflux of the solution, and then keep constant temperature React for 6 hours, cool the reaction to room temperature, filter the crude product after precipitation, wash with deionized water until neutral, put the obtained crude product in a vacuum drying oven for drying, and use column chromatography to separate and purify the dried crude product , to obtain monomer M1; the vacuum drying temperature is 80-85°C, the vacuum drying time is 12h, and the vacuum drying pressure is -30--29KPa;

[0072] (2) Preparation of monomer M2 (N,N-bis(4-bromophenyl)-N-(4-methoxy)aniline): 1.70g (13.83mmol) 4-methoxyaniline, 8.08g ...

[0079] Example 2 Terpolymer is used to prepare electric storage device

[0080] In the present invention, the terpolymer prepared in Example 1 is used as an organic layer to prepare an electric storage device. The structure diagram of the electric storage device is as follows figure 1 As shown, it includes a substrate layer, a cathode layer, an organic layer and an anode layer, the cathode is disposed on the substrate, the organic layer is disposed on the cathode, and the anode is disposed on the organic layer.

[0081] The organic layer of the present invention is formed from the terpolymer prepared in Example 1, and the terpolymer is used to make storage materials for electric storage devices. In the terpolymer, the electron-rich fluorenyl and triphenylamine groups are excellent electron-donor units, and the introduction of electron-donating groups into the main chain of the polymer can effectively improve the hole transport ability of the polymer, making the copolymerizati...

Abstract

The invention belongs to the technical field of organic electric storage materials, and discloses an alkoxy-containing triphenylamine donor group terpolymer, an electric storage device and preparationthereof. The terpolymer has the following structure: in the formula, R is alkoxy, R1 is alkyl, m is an integer from 20 to 300, and n is an integer from 20 to 300. The electric storage device comprises an organic layer being the terpolymer, and further comprises a substrate, a cathode and an anode. The invention also discloses preparation methods of the terpolymer and the electric storage device.The terpolymer provided by the invention has strong conjugation degree and hole transport capability, reduces the turn-on voltage, improves the switching current ratio, improves the storage density, and is easy to form a film. The prepared electric storage device is low in turn-on voltage, low in energy consumption, high in switching current ratio, high in resolution ratio, low in misreading rate,capable of quickly responding and performing repeated cyclic reading and writing, and excellent in performance.

Description

technical field [0001] The invention belongs to the technical field of organic storage materials, and in particular relates to a terpolymer containing alkoxy triphenylamine donor groups and a synthesis method thereof, and an electric storage device using the polymer as an organic layer and a preparation method thereof. Background technique [0002] With the advent of the information age, the amount of information people face in their daily lives is increasing rapidly, and traditional storage technologies are no longer able to meet the basic needs of storing information. Therefore, electrical storage with better performance is indispensable. The technology of using traditional inorganic semiconductor materials to prepare electrical storage devices has been very mature, making it fully applied in various information fields. As the increasing demands of mobile applications continue to drive the continuous development of storage technologies and devices, there is an increasing ...
