英文摘要： The studies of the booming metal-organic framework materials have the significantly potential applications in the basic research filed and, therefore, have attracted the great attentions for the global chemical workers and materials scientists in recent years. In this project, two different series of organic ligands decorated by the functional substituted groups will be rationally designed and prepared for meeting the special functional requirements of the pre-synthesizing materials. The functional materials will be yielded by employing the microwave-assisted synthesis. Some contents of the obtained materials, such as the synthesis conditions, crystal structures, the features of the pores, adsorption and catalysis etc, will be systemically investigated. The project will strive to explore the regulations between the functional substituted groups of the ligands and the pore size and properties of the materials and the influenced rules of the composition and performance, build the structure-property relationship. Then it will reveal that how the spatial stacking fashions of the organic ligands direct macroscopic properties of the materials, and deepen the understanding of the functional features of the materials and the nature of the organic ligands. And finally, the project will supply some valuable experimental m
