Abstract

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.

含有双（羟基苯基）蒽衍生物的锆基金属有机框架：分子设计、合成、晶体结构和甲烷吸附作用

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
