我们结合了目标化学和计算设计，为多孔对苯二甲酸铬MIL-101创建了一个晶体结构，具有非常大的孔径和表面积。其沸石型立方结构具有巨大的晶胞体积（约702，000立方埃），超大孔径等级（0.30至34埃），N2的朗缪尔表面积为0.5900 ± 300平方米/克。除了多孔化合物的通常特性外，这种固体还具有作为单分散纳米材料纳米模具的潜力，如这里通过在笼内引入Keggin聚阴离子所示。
We combined targeted chemistry and computational design to create a crystal structure for porous chromium terephthalate, MIL-101, withverylargeporesizes and surface area. Its zeotype cubic structure has a giant cell volume (∼702,000 cubic angstroms), a hierarchy of extra-large pore sizes (∼30 to 34 angstroms), and a Langmuir surface area for N2of ∼5900 ± 300 square meters per gram. Beside the usual properties of porous compounds, this solid has potential as a nanomold for monodisperse nanomaterials, as illustrated here by the incorporation of Keggin polyanions within the cages.
