    • The present invention provides porous metal-organic polyhedra. The porous metal-organic polyhedra of the present invention comprises a plurality of metal clusters each of which have two or more metal ions, and a sufficient number of capping ligands to inhibit polymerization of the metal organic polyhedra. The porous metal-organic polyhedra further includes a plurality of multidentate linking ligands that connect adjacent metal clusters into a geometrical shape describable as a polyhedral with metal clusters positioned at one or more vertices of the polyhedron. The present invention also provides a method of making the porous metal-organic polyhedra in which a solution comprising a solvent, one or more ions, and a counterions that complexes to the porous metal-organic polyhedra as a capping ligand to inhibit polymerization of the metal organic polyhedra, with a multidentate linking ligand.

    • The ability to design and construct solid-state materials with pre-determined structures is a grand challenge in chemistry. An inventive strategy based on reticulating metal ions and organic carboxylate links into extended networks has been advanced to a point that allows the design of porous structures in which pore size and functionality can be varied systematically. MOF-5, a prototype of a new class of porous materials and one that is constructed from octahedral Zn-O-C clusters and benzene links, was used to demonstrate that its 3-D porous system can be functionalized with the organic groups, -Br, -NH2, -OC 3 H 7 , -OC 5 H 11 , -H 4 C 2 and -H 4 C 4 , and its pore size expanded with the long molecular struts biphenyl, tetrahydropyrene, pyrene, and terphenyl. The ability to direct the formation of the octahedral clusters in the presence of a desired carboxylate link is an essential feature of this strategy, which resulted in the design of an isoreticular (having the same framework topology) series of sixteen well-defined materials whose crystals have open space representing up to 91.1% of the crystal volume, and homogeneous periodic pores that can be incrementally varied from 3.8 to 28.8 angstroms. Unlike the unpredictable nature of zeolite and other molecular sieve syntheses, the deliberate control exercised at the molecular level in the design of these crystals is expected to have tremendous implications on materials properties and future technologies. Indeed, data indicate that members of this series represent the first monocrystalline mesoporous organic/inorganic frameworks, and exhibit the highest capacity for methane storage (155 cm 3 /cm 3 at 36 atm) and the lowest densities (0.41 to 0.21 g/cm 3 ) attained to date for any crystalline material at room temperature.
    • 使用预定结构设计和构建固态材料的能力是化学领域的一大挑战。 基于将金属离子和有机羧酸盐连接网络化成扩展网络的创新策略已经进展到允许孔径​​和功能性可以系统地变化的多孔结构的设计。 MOF-5是一种新型多孔材料的原型,由八面体Zn-OC簇和苯环构成的原型,用于证明其3-D多孔体系可以用有机基团-Br, -NH2,-OC3H7,-OC5H11,-H4C2和-H4C4,其孔径用长分子支链联苯,四氢苯乙烯,芘和三联苯扩展。 在存在所需的羧酸酯键的情况下引导形成八面体簇的能力是该策略的基本特征,其导致设计了十六种明确定义的材料的晶体(具有相同的框架拓扑)系列,其晶体 具有高达91.1%晶体体积的开放空间,并且均匀的周期性孔隙可以逐渐变化,从3.8到28.8埃。 与沸石和其他分子筛合成的不可预知的性质不同,在分子水平上对这些晶体的设计进行有意的控制预计对材料性能和未来技术有巨大的影响。 事实上,数据表明,这一系列的成员代表了第一个单晶介孔有机/无机骨架,并且表现出最高的甲烷储存能力(36 atm时为155 cm 3 / cm 3),最低密度为0.41〜0.21 g / cm 3)在室温下达到任何结晶物质。
