The Synthesis and Magnetic Properties of Metal Complexes of Polymethyl Methacrylate Containing Terpyridine

以4'-(4-羟苯基)-2,2':6',2″-三联吡啶为原料合成了均聚物聚[4'-(4-甲基丙烯酰氧基苯基)-2,2':6',2″-三联吡啶](PmPhtpy),并制备了其与Co2+、Ni2+及Nd3+的高分子螯合物PmPhtpy-Co2+、PmPhtpy-Ni2+和PmPhtpy-Nd3+.聚合物及螯合物结构通过核磁共振、红外光谱和GPC进行了表征确证.螯合物PmPhtpy-Co2+、PmPhtpy-Ni2+和PmPhtpy-Nd3+的磁性能测试结果表明:PmPhtpy-Co2+和PmPhtpy-Ni2+是有机软铁磁体,PmPhtpy-Nd3+是有机软亚铁磁体.
Poly[4'-(4-methacryloyphenyl)-2,2':6',2″-terpyridine] and its three complexes PmPhtpy-Co2+,PmPhtpy-Ni2+,PmPhtpy-Nd3+ are synthesized using 4'-(4-methacryloyphenyl)-2,2':6',2″-terpyridine as the substrate.Their structures are fully confirmed by 1H NMR,FT-IR,and GPC.The magnetic behavior is measured as a function of the magnetic field strength at 30 kOe and as a function of temperature(5-300 K).The magnetic hysteresis loops of the complexes show a typical "S" shape at 5 K,which suggested soft ferromagnetic properties
