基于手性配体的铼配合物发光和铁电性能研究

The photoluminescent and ferroelectric properties of chiral lanthanide complexes based on N-hybrid chiral ligands have attracted the attention from some research groups. But the photoluminescence and ferroelectricity investigation on chiral rhenium(I) complexes from these ligands are rare reported. The study of the chiral rhenium(I) complexes not only can broad the area of the ferroelectric materials, but also can obtain some materials with multifunctional properties. Therefore, in this program we designed some chiral ligands such as bipyridine, pyrazine and 2,2':6',2''-terpyridine derivatives with chiral pinene moieties, chiral oxazoline and chiral Schiff base. Using these ligands, some chiral rhenium(I) complexes can be prepared. Then from the photoluminescent and ferroelectric property investigation of these complexes, we try to found the law of the property with the ligand and complex molecular structure. From the research we hope the results can guide us to design the new chiral ligands and complexes. At the end, we can obtain some useful chiral rhenium(I) complexes with good multifunctional properties.

基于手性含氮配体的稀土配合物进行发光和铁电性质的研究取得了一定的进展，但是对于利于这些手性配体合成铼配合物而开展铁电性能的研究还少有报道。合成此类配合物不仅可以拓展铁电材料的研究范围，而且有可能获得多功能材料，有重要的学术和应用研究价值。因此，本项目通过调控配体共轭体系的大小、刚性程度、取代基的种类设计了系列含氮手性配体如手性蒎烯联吡啶类、手性蒎烯吡嗪类、手性蒎烯三联吡啶类、手性双噁唑啉类、吡啶单噁唑啉类和手性希夫碱类配体等和相应的铼配合物。通过深入研究配合物的光致发光和铁电性能，探索材料的分子结构和种类与性能之间的规律，为新型手性配体和铼配合物的设计开发提供实验数据，从而开发出同时具有优良发光和铁电等性能的多功能铼配合物。
