中文摘要: 金属有机框架(MOFs)将无机金属离子和有机配体结合在一起,是一类新型的无机-有机杂化材料,其在光学性能方面具有十分诱人的应用前景。此外,纳米材料由于其尺寸较小而具有诸多独特的性能,且更利于实际应用。本项目拟通过溶剂热等合成法,选用有机多齿配体和过渡或稀土金属离子构筑新颖的MOFs材料,并采用不同的方法将其纳米化,进而表征它们的分子结构和各种物理化学性质,重点研究晶体MOFs材料和纳米MOFs材料在光学性能方面的差异。

英文摘要: Metal-organic frameworks (MOFs) are a new type of inorganic-organic hybrid material, which combine the inorganic metal ions and organic ligands, and have a very attractive application prospect in the luminescent properties. Moreover, nano-materials possess lots of unique properties since their smaller size, and more conducive to practical application. In this project, organic multidentate ligands and transition metal ions or lanthanide ions were selected to construct novel MOF materials through solvothermal methods. And choosing different methods to obtain nano-crystals, and then characterize their molecular structures and various physical and chemical properties, and focusing on the difference of luminescent properties between crystal-MOFs and nano-MOFs.
