中文摘要: 面对当前知识创新和节能减排的重要需求,微孔金属有机框架材料备受关注。本项目针对沸石分子筛微孔结构,以发展一类新的断键型类沸石硼咪唑框架材料为研究目标,研究断键型类沸石硼咪唑框架材料在温室气体二氧化碳的捕捉、储存,小分子化工原料的节能催化等方面的功能应用。首先应用结构设计思想,利用三连接的有机硼咪唑配体和四面体配位的金属离子合成断键型类沸石分子筛框架材料,因为断键的存在,能有效的扩大结构中的分子环和增强其应用功能;同时,在大量合成工作的基础上,总结功能-结构-合成三者之间的关系与规律,发展一套断键型类沸石硼咪唑框架材料的设计方法和定向合成路线,探索适用于二氧化碳俘获或小分子催化的新型功能材料。

英文摘要: Porous Metal-organic framworks (PMOFs) with zeoltype topologies continues to attract much attention in some currently emerging areas related to health, energy use, and environmental conservation. The project focuses on design and synthesis of a new kind of PMOFs which are based on the the assembly of BH(im)3 unit with tetrahedral metal centers. From this strategy, some interesting interrupted zeolitic boron imidazolate frameworks with lower connectivity (3-connected) have been prepared in our former research. This project is to further investigate the network diversity of such interrupted frameworks and their potential applications in gas sorption and catalysis. From this project, we will carefully analysis the relationship between the structures and properties of such materials. Several highly effective materials for CO2 uptake might be developed and several SCI papers with high impact factors could be published.
