使用壳聚糖作为形态结构导向剂合成了分子磁性材料钴普鲁士蓝。生物聚合物的强螯合能力确保无机相保持纳米颗粒状态。 SQUID 磁力测量表明，纳米颗粒在 16 K 时表现出急剧的亚铁磁到顺磁转变。
The molecular magnet material, cobalt-Prussian Blue, has been synthesized using chitosan as a morphological structure-directing agent. The strong chelating ability of the biopolymer ensures that the inorganic phase remains nanoparticulate. SQUID magnetometry reveals that the nanoparticles exhibit a sharp ferrimagnetic to paramagnetic transition at 16 K.
