Study on properties and synthesis of polymer schiff base with ferrocene and bi-thiazole

The DABT was synthesized with 2, 3-butanedione, liquid dibromine, and thiourea and the ferrocenyl schiff base was synthesized by DABT and ferrocenecarboxaldehyde. Then polymer of ferrocenyl schiff base was prepared by the Friedel-Crafts method, their metal complexes were made by doping Fe²⁺, Ni²⁺ and Cu²⁺sulfates. Their structures were characterized by infrared spectra and ¹H-NMR spectra, conductivity and magnetism properties were measured with a Four-point probe Instrument and gouy magnetic balance. The experiment results showed that the synthetical product was polymer of ferrocenyl schiff base, its conductivity was 1.61×10^-6 S·cm^-1 belonging to semiconductor. Magnetism properties of metal complexes by doping Fe²⁺, Ni²⁺ and Cu²+ sulfates were obviously higher than polymer of un-doping, and properties of complexes by doping Cu²⁺sulfate was best. These properties indicated they can be applied as a new organic functional electromagnetism material.
