摘要： 自旋转换配合物(又称自旋交叉配合物)由于可用作分子基电子器件材料而受到科学家的广泛关注[1～4].近年来,虽然发现了一些具有自旋交叉现象的Fe(Ⅱ)配合物,但其转换温度多在液氮温度以下且无滞后现象,不能满足实用信息存储材料的要求。

关键词: Fe(Ⅱ)配合物, 自旋转换, 滞后, 热致变色

Abstract: Spin transition complexes are of great interest because of their potential application in molecular based electronic devices such as optical memory and switches. Anovel linear polynuclear spin transition complex[Fe(PhCH=Ntrz)3](BF4)2·3H2O(where PhCHNtrz stood for the Schiff base condensed by 4-NH2-1,2,4-triazole and benzaldehyde) was synthesized and characterized by elemental analysis, molar conductance, IR and UV-V is spectra, magnetic measurements and temperature-dependence optical detection. The spin transition occurred at 105～235 K with hysteresis and pronounced thermochromism. TC↑=180 K, TC↓=169 K, hysteresis width 11 K.

Key words: Iron(Ⅱ) complex, Spin transition, Hysteresis, Thermochromism
