چکیده انگلیسی
The polymer (DAPcTPA) was synthesized by polycondensation of 5,6-diamine-1,10-phenanthroline (DAP) with terephthaldehyde (TPA). Three polymeric complexes were first prepared from polymer (DAPcTPA) and NiSO4, CoCl2 or FeSO4, respectively. The structures of polymer and complexes were characterized by IR, 1H NMR spectra and elemental analysis. The magnetic behavior of these complexes was measured as a function of magnetic field strength (0–50 kOe) at 5 K and as a function of temperature (5–300 K) at a magnetic field strength of 30 kOe. The results show that DAPcTPA-Ni2+ and DAPcTPA-Co2+ are soft ferromagnets, while DAPcTPA-Fe2+ exhibits features of an antiferromagnet.
