摘要

A novel linear polymer (PFABT) containing bithiazole rings was synthesized by polycondensation of 2,2'-diamino-4,4'-bithiazole (DABT) and formaldehyde. The complexes of PFABT with two transition metal ions (Fe{sup}(2+), Cu{sup}(2+)) were prepared for the first time. The polymer was determined through FT-IR, 1{sup left}H-NMR and elemental analysis (EA), and the complexes were characterized by FT-IR. The magnetic behaviors of these complexes were measured as a function of magnetic field strength (0-50 kOe) at 4K and as a function of temperature (4-300 K) under an applied magnetic field of 30 kOe. The results show that PFABT-Cu{sup}(2+) is a ferromagnet while PFABT-Cu{sup}(2+) is an anti-ferromagnet.
