摘要

研究人员设计了一种金属有机框架（MOF），该框架由锆簇和双(羟基苯基)蒽连接体 Zr6O4(OH)4(adhb)6（adhb：4,4′-(蒽-9,10-二基)双(2-羟基苯甲酸)组成，可使甲烷储存量达到 300 克，并且无需使用高压釜即可批量合成。这种 MOF 具有 1,818 m2/g 的大比表面积和 0.78 cm3/g 的空隙率，因此在 294 K 和 9.8 bar 条件下可吸附 65.4 cm3STP/cm3 和 4.7w% 的甲烷。此外，八面体笼模型表明，蒽环为甲烷的加入提供了合适的孔隙入口和立体阻碍。

Zirconium-based metal-organic framework with bis(hydroxyphenyl)anthracene derivative: molecular design, synthesis, crystal structures, and methane adsorption

A metal-organic framework (MOF) composed of a zirconium cluster with a bis(hydroxyphenyl)anthracene linker, Zr6O4(OH)4(adhb)6 (adhb: 4,4′-(anthracene-9,10-diyl)bis(2-hydroxybenzoic acid), was designed to achieve methane storage up to 300 g and batch synthesized without using an autoclave. This MOF can adsorb 65.4 cm3STP/cm3 and 4.7w% of methane at 294 K and 9.8 bar due to its large specific surface area of 1,818 m2/g and void fraction of 0.78 cm3/g. Furthermore, an octahedral cage model indicated that the anthracene ring provides a suitable pore entrance and steric hindrance for methane inclusion.
