1. A preparation method of an asymmetric organic polymer, comprising:
dissolving, in a 25 mL three-necked bottle, 80 mg of compound 8 and 137 mg of compound 9 in a mixture of 4.5 mL of toluene and 0.5 mL of N, N-dimethylformamide, bubble with nitrogen for 15 minutes;
adding 5.17 mg of Pd2 (dba) 3 and p-(o-tol) 6 mg;
heating and refluxing for 4 hours to produce a solution;
stopping the heating immediately after the solution is viscous;
cooling the solution, and loading the solution into 100 mL of anhydrous methanol for sedimentation;
filtering by suction;
using a Soxhlet extractor for purification; and
using column chromatography for secondary purification to obtain 100.1 g of blue-black solid, wherein the reaction formula is as follows:
