What are the characteristics of Schiff base, such as chelation, heat resistance, liquid crystal and intrinsic conductivity. The conductivity of Conjugated Poly (Schiff base) doped with iodine can be increased by about 8 orders of magnitude, which makes it reach the level of semiconductor. The doped materials have good stability, electrochemical activity and photoconductivity.

In the conventional state, the molecular chain of poly (Schiff base) is relatively rigid, and the intermolecular force is also strong, so the polymer is insoluble and insoluble. However, the Schiff base synthesized by using trimethylol aminomethane and other solvents directly makes the Schiff base get rid of the difficult situation of polymer processing and characterization, and the conductivity increases.

In order to improve the yield of Schiff base, it is necessary to synthesize Schiff base by the reaction of 3,5-dibromosalicylic aldehyde with trimethylolminomethane, and reduce Schiff base with anhydrous ethanol at room temperature. The results showed that the molar ratio of 3,5-dibromosalicylic aldehyde to trihydroxymethylaminomethane was 1 â?¶ 1, the reaction time was 30 min, the molar ratio of sodium borohydride to 3,5-dibromosalicylic aldehyde trihydroxymethylaminomethane Schiff base was 1.5 1, and the yield of reduced Schiff base was 81.4%.
