摘要

液态烃的分离和提纯是生产各种石化原料的重要环节。然而，这些碳氢化合物之间的结构和化学相似性使得传统的分离方法（如蒸馏和提取）既具有挑战性，又耗费大量能源。利用多孔固体吸附剂进行吸附分离是一种很有前途的节能方法。其中，柔性金属有机骨架（fmof）作为mof的一个分支，已经成为一种无与伦比的多孔材料，用于基于高选择性吸附的液态烃分离和纯化。由于具有内在的动态结构，与刚性MOFs （RMOFs）相比，FMOFs表现出非常不同的吸附行为，刚性MOFs （RMOFs）在激活时不涉及结构转变，以及分子吸附。

Flexible Metal–Organic Frameworks for Adsorptive Separation of Liquid Hydrocarbons

The separation and purification of liquid hydrocarbons are vital for producing various petrochemical feedstocks. However, the structural and chemical similarities among these hydrocarbons make conventional separation methods such as distillation and extraction both challenging and energy intensive. Adsorptive separation using porous solid adsorbents presents a promising and energy-efficient alternative. Among these, flexible metal–organic frameworks (FMOFs) as a subgroup of MOFs have emerged as an unparalleled class of porous materials for highly selective adsorption-based separation and purification of liquid hydrocarbons. Having intrinsically dynamic structures, FMOFs exhibit very different adsorption behaviors compared to rigid MOFs (RMOFs), those that do not involve structure transformations upon activation, and molecular adsorption.

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.
