Embodiment 1
[0041] This embodiment provides a conjugated polymer based on benzobisthienediazole, the general structure of which is shown in formula (I);
[0042]
[0043] In said structural formula I, R 1 and R 2 Each independently represents hydrogen, C 1 -C 30 Alkyl, C 1 -C 30 Alkoxyl, C 6 -C 30 Aryl, 5-30 membered heteroaryl; n is an integer greater than or equal to 4 and less than 20.
[0044] Preferably, in the formula I structure, R 1 means C 1 -C 30 the alkyl group, R 2 means C 1 -C 30 alkoxy;
[0045] Preferably, in the formula I structure, R 1 means C 6 -C 30 the alkyl group, R 2 means C 6 -C 30 alkoxy;
[0046] Preferably, in the formula I structure, R 1 means C 6 -C 18 straight chain alkyl or C 8 -C 30 branched chain alkyl, R 2 means C 6 -C 18 straight-chain alkoxy or C 8 -C 30 branched chain alkoxy groups.
[0047] The chemical formula of the conjugated polymer of the present embodiment is specifically as formula (II)

Embodiment 2
[0051] This example provides a method for preparing the polymer PBBT-2OT represented by the above formula (II).
[0052] (1) Protected by inert gas, under the catalysis of tris(dibenzylideneacetone) dipalladium and tris(o-methylphenyl)phosphorus, 4,8-Bis[5-bromo-4-(2-octyldodecyl )-2-thienyl]-2λ4δ2-benzo[1,2-c:4,5-c']-bis[1,2,5]th iadiazole (M1) with 1,1'-[4,4'- Bis (dodecyloxy)[2,2'-bithiophene]-5,5'-diyl]bis[1,1,1-trimethylstannane](M2) was mixed solution in organic solvent.
[0053]In this method, 4,8-Bis[5-bromo-4-(2-octyldodecyl)-2-thienyl]-2λ4δ2-benzo[1,2-c:4,5-c']-bis[1,2 ,5]th iadiazole to 1,1'-[4,4'-Bis (dodecyloxy)[2,2'-bithiophene]-5,5'-diyl]bis[1,1,1-trimethylstannane] molar ratio It is 1:0.99-1.05, preferably 1:1. The amount of tris(dibenzylideneacetone)dipalladium is 4,8-Bis[5-bromo-4-(2-octyldodecyl)-2-thienyl]-2λ4δ2-benzo[1,2-c:4,5- c']-bis[1,2,5]th iadiazole molar dosage of 2-4%, the dosage of tris(o-methylphenyl)phosphorus is 4,8-Bis[5-bromo-4-(2-octyldod...
Embodiment 3
[0058] The third embodiment provides a specific method for the polymer PBBT-2OT represented by the above formula (II).
[0059]
[0060] First of all, it is stated that M1 and M2 in the above formula are the reactants M1 and M2 respectively.
[0061] Under nitrogen protection, in a 15ml Schlenk tube, add 107.7mg (0.10mmol) of compound M1, 74.9mg (0.10mmol) of compound M2, 3.6mg (4mol%) of Pd2(dba)3, 2.4mg (8mol) %) of P-(o-Tol), 2.0ml of chlorobenzene, stirred and reacted at 145° C. for 3 days.
[0062] Then use 2-tributylstannylthiophene and 2-bromothiophene to stop the reaction successively.
[0063] Then, the reaction mixture solution was added dropwise into 200 ml of methanol, and a solid was precipitated and dried to obtain 120 mg of the product, with a crude yield of 89.5%.
[0064] Finally, the crude product was subjected to Soxhlet extraction in the order of acetone, n-hexane, tetrahydrofuran and chloroform, and the chloroform component was concentrated and added ...
