摘要: 设计制备了一个新的常温自旋交叉配合物[Fe(dpp)(Mepy)2(NCS)2]。通过元素分析、红外光谱、电喷雾质谱和紫外光谱等方法对该配合物进行结构表征。变温磁化率研究发现该配合物的自旋转换温度Tc为330K。通过与同体系其他配合物的比较发现,配体的修饰对自旋交叉临界温度以及回滞宽度都有显著影响。

Abstract: A new room-temperature spin crossover complex [Fe(dpp)(Mepy)2(NCS)2] was prepared. Elemental analysis, infrared spectrum, electrospray ionization mass spectrum and ultraviolet spectrum were used to study the structure of the complex. The temperature dependence of magnetic susceptibility shows that the temperature of spin transition is 330K. By comparing the complex with the other resemble structural complexes, it reveals that the modification of ligand will influence the critical temperature and hysteresis loop of spin crossover greatly.

Key words: magnetic susceptibilities, spin crossover, spin transition, molecule material
