Embodiment 1 3
[0070] The preparation of embodiment 1 terpolymer:
[0071] (1) Preparation of monomer M1 (9,12-dibromo-7H-benzimidazo(2,1-a)benzo(de)isoquinolin-7-one): in N 2 Under the atmosphere, 1.8-naphthalenedicarboxylic anhydride and 3,6-dibromo-1,2-phenylenediamine were added in a molar ratio of 1:1, and 10 mL of glacial acetic acid was placed in a three-necked flask, stirred and heated to the reflux of the solution and then kept at a constant temperature. The reaction was carried out for 6 h, the reaction was cooled to room temperature, the crude product was precipitated and filtered, washed with deionized water until neutral, and the obtained crude product was placed in a vacuum drying oven for drying, and the dried crude product was separated and purified by column chromatography , to obtain monomer M1; the temperature of the vacuum drying is 80~85℃, the time of vacuum drying is 12h, and the pressure of vacuum drying is -30~-29KPa;
[0072] (2) Preparation of monomer M2 (N,N-bis(4...

[0079] Example 2 Terpolymers are used to prepare electrical storage devices
[0080] In the present invention, an electrical storage device is prepared by using the terpolymer prepared in Example 1 as an organic layer. The electrical storage device, the schematic structural diagram 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 arranged on the substrate, the organic layer is arranged on the cathode, and the anode is arranged 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 a storage material for an electrical storage device. In terpolymers, electron-rich fluorene groups and triphenylamine groups serve as excellent electron-donating groups. The introduction of electron-donating groups into the main chain of the polymer can effectively improve the hole transport ability of the polym...
