磁性簇合物含有有限数量的顺磁金属离子，具有确定的拓扑结构以及磁制冷和单分子磁体等性质。本项目针对磁性簇合物的应用，通过超分子组装来构筑功能集成的簇基共轭高分子杂化材料，以及材料自组装形成多级有序纳米结构。一、通过端基带有离子基团的共轭高分子和相反电荷的磁性簇合物的静电自组装，构建以磁性簇合物为核，以共轭高分子为支链的超分子星状聚合物。这类组装体可视作共轭星状聚合物的模型体系。二、在改变溶剂质量的溶液体系中，研究这些模型共轭星状聚合物之内、之间的共轭高分子链段间相互作用和自组装纳米结构，揭示它们的自组装机制，可控实现磁性簇合物在共轭高分子体系中的有序排列。三、在研究自组装行为的同时，详细研究与之相对应的光物理性质和磁性，阐明杂化星状聚合物的超分子结构、自组装纳米结构与功能特性三者间的内在联系。该研究将磁性簇合物和共轭高分子的可加工性、发光结合在一起，将为磁性簇合物的进一步器件化提供知识基础。

Magnetic clusters contain a finite number of paramagnetic metal ions, possess well-defined topological structures and exhibit intriguing magnetic properties such as magnetic cooling and single-molecule magnet behaviours. Their real applications require fabricating cluster-based conjugated polymer hybrids with function combination by using supramolecular self-assembly. The resulting materials further self-assemble into hierarchical nanostructures, often through solution-based processes. (i) We will prepare and characterize a series of supramolecular starlike polymers, in which the cores are magnetic clusters and the arms are conjugated polymers. Because of the highly similar architecture, such assemblies can be regarded as a model of conjugated starlike polymers. (ii) Accordingly, intra- and inter-star interactions between the segments of the conjugated arms and self-assembled behaviors of the model conjugated star polymers in solvents of variable quality will be studied systematically, where the self-assembled mechanism is then clarified in detail. (iii) Meanwhile, the photophysical and magnetic properties are investigated correspondingly. And therefore, we will build a substantial relationship among supramolecular structures, self-assembled structures and functional properties. The present concept concerning a combination of magnetic clusters with conjugated starlike polymers will open a new avenue to develop cluster-based functional materials and devices.
