摘要：

A novel bithiazole oligomer (PCBT) was synthesized from C-60 and the diazo salt of 2,2'-diamino-4,4'-bithiazole (DABT). Its ferro-complex (PCBT-Fe2+) was prepared from PCBT and FeSO4 in DMSO solution under a purified nitrogen atmosphere. The magnetic behavior of PCBT and PCBT-Fe2+ was measured as a function of magnetic field strength (0-60kOe) at 5 K and as a function of temperature (5-300 K) at a magnetic field strength of 30 kOe. PCBT-Fe2+ complex exhibits a hysteresis cycle at 5 K, the observed coercive field (Hc) and remriant magnetization (M-r) are 690 Oe and 0. 12 emu/g, respectively. The results show that PCBT is an anti-ferromagnet and its Fe2+-complex is a soft ferromagnet. (C) 2001 Published by Elsevier Science Ltd.
