Abstract

The magnetic behaviour of Mn 12 -stearate single-molecule magnets (SMMs) ([ Mn 12 O 12 ( CH 3 ( CH 2 ) 16 CO 2 ) 16 ] · 2 CH 3 COOH · 4 H 2 O ) on the surface of 300 nm spherical silica nanoparticles were investigated. The SMMs were bonded at the silica surface with the assumed number of anchoring points, which influenced on their degree of freedom and distribution. In order to check the properties of Mn 12 -stearate molecules separated on the silica surface, and check their interactions, the samples containing four different concentration of spacers per single anchoring unit and variously bonded Mn 12 -stearate particles were prepared. The materials have been examined using Raman spectroscopy, transmission electron microscopy, and SQUID magnetometry. The results of magnetic measurements showed a correlation between the way of single-molecule magnets immobilization onto the silica spheres and the magnetic properties of the obtained hybrid materials.

摘要

研究了300 nm球形二氧化硅纳米颗粒表面的Mn12 - 硬脂酸单分子磁体（SMMs）（[Mn12O12(CH3(CH2)16CO2)16]·2CH3COOH·4H2O）的磁行为。SMMs以假定数量的锚定点键合在二氧化硅表面，这影响了它们的自由度和分布。为了检查在二氧化硅表面分离的Mn12 - 硬脂酸分子的性质，并检查它们之间的相互作用，制备了每个单锚定单元含有四种不同浓度间隔物以及不同键合的Mn12 - 硬脂酸颗粒的样品。使用拉曼光谱、透射电子显微镜和超导量子干涉仪磁力计对这些材料进行了检测。磁性测量结果表明，单分子磁体固定在二氧化硅球上的方式与所得杂化材料的磁性之间存在相关性。
