Core/shell and core/shell/shell particles comprised of the Prussian blue analogues K(j)Ni(k)[Cr(CN)(6)](l)·nH(2)O (A) and Rb(a)Co(b)[Fe(CN)(6)](c)·mH(2)O (B) have been prepared for the purpose of studying persistent photoinduced magnetization in the heterostructures. Synthetic procedures have been refined to allow controlled growth of relatively thick (50-100 nm) consecutive layers of the Prussian blue analogues while minimizing the mixing of materials at the interfaces. Through changes in the order in which the two components are added, particles with AB, ABA, BA, and BAB sequences have been prepared. The two Prussian blue analogues were chosen because B is photoswitchable, and A is ferromagnetic with a relatively high magnetic ordering temperature, ~70 K, although it is not known to exhibit photoinduced changes in its magnetic properties. Magnetization measurements on the heterostructured particles performed prior to irradiation show behavior characteristic of the individual components. On the other hand, after irradiation with visible light, the heterostructures undergo persistent photoinduced changes in magnetization associated with both the B and A analogues. The results suggest that structural changes in the photoactive B component distort the normally photoinactive A component, leading to a change in its magnetization. 相似文献

应用电化学原位偏振红外反射光谱法研究了构建于金(111)电极表面的浮动磷脂双层膜.金电极表面先自组装一层巯基葡萄糖单层来增加表面的亲水性,浮动磷脂双层膜通过LB-LS技术构建在巯基葡萄糖单层上.双层膜由双肉豆蔻磷脂酰胆碱(DMPC)、胆固醇和神经节苷脂GM1构成.GM1分子中的糖链可以物理吸附在巯基葡萄糖表面,在双层膜和基底间形成一个富含水的隔层.红外光谱表明浮动双层膜中的DMPC分子比传统的支撑双层膜中的DMPC分子有更强的水合作用,证实了双层膜和基底间水层的存在.该浮动双层膜更接近于实际的生物膜体系,并且在金电极表面有宽的电位区间,非常适于进一步的离子通道蛋白质研究. 相似文献
