Metal–Organic Framework MIL-101 for HighResolution Gas-Chromatographic Separation of Xylene Isomers and Ethylbenzene
• We show the first fabrication of the MOFcoated capillary column for high-resolution GC separation. • we choose MIL-101 as the stationary phase and xylene isomers and ethy-lbenzene (EB) as the targets for separation.

Design and synthesis of an exceptionally stable and highly porous metal-organic framework
• In this paper, IRMOF1 is tested as an adsorbent for preconcentration for the first time using dimethyl meth-ylphosphonate (DMMP) as a test case.

This synthesis is achieved by borrowing ideas from metal carboxylate cluster chemistry, where an organic dicarboxylate linker is used in a reaction that gives supertetrahedron clusters when capped with monocarboxylates.

Metal Organic Frameworks as Adsorbents for Trapping and Preconcentration of Organic Phosphonates
金属有机骨架材料及其 应用
研究背景
金属有机骨架（MOFs）是由含氧、氮等的 多齿有机配体（大多是芳香多酸和多碱） 与过渡金属离子自组装而成的配位聚合物
早在20世纪90年代 中期，第一类MOFs 就被合成出来，但 其孔隙率和化学稳 定性都不高
目前，已经有大量 的金属有机骨架材 料被合成，这些金 属有机骨架中多数 都具有高的孔隙率 和好的化学稳定性
Omar M. Yaghi received his Ph.D. from the University of Illinois-Urbana (1990) with Professor Walter G. Klemperer. He was an NSF Postdoctoral Fellow at Harvard University (1990-92) with Professor Richard H. Holm. He has been on the faculties of Arizona State University (1992-98) and University of Michigan (1999-2006). His current position is the Jean Stone Professor of Chemistry at UCLA.
