摘要

样品制备在分析化学中至关重要,会影响结果的准确性、灵敏度和可靠性。固相分离介质,尤其是吸附剂,对于制备大多数分析仪器常用的液体和气体样品至关重要。近年来,随着材料科学的发展,通过强共价键构建的共价有机框架(COFs)越来越多地被用于样品制备。COF 具有较大的比表面积、可调的孔径、易于改性和稳定的化学性质,因此对单一目标物或从复杂基质中选择性地吸附多个目标物具有突出的选择性和/或出色的吸附能力。在这篇综述中,我们总结了 COFs 的分类,如原始 COFs、COF 复合颗粒和基于 COFs 的基质。我们旨在全面了解近三年来 COF 在样品制备中的不同分类。此外,还介绍了 COFs 在样品制备中面临的挑战和发展趋势。

Advances in covalent organic frameworks for sample preparation
Sample preparation is crucial in analytical chemistry, impacting result accuracy, sensitivity, and reliability. Solid-phase separation media, especially adsorbents, are vital for preparing of liquid and gas samples, commonly analyzed by most analytical instruments. With the advancements in materials science, covalent organic frameworks (COFs) constructed through strong covalent bonds, have been increasingly employed in sample preparation in recent years. COFs have outstanding selectivity and/or excellent adsorption capacity for a single target or can selectively adsorb multiple targets from complex matrix, due to their large specific surface area, adjustable pore size, easy modification, and stable chemical properties. In this review, we summarize the classification of COFs, such as pristine COFs, COF composite particles, and COFs-based substrates. We aim to provide a comprehensive understanding of the different classifications of COFs in sample preparation within the last three years. The challenges and development trends of COFs in sample preparation are also presented.

期刊介绍: The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
