Bromine-Functionalized Covalent Organic Frameworks Enhancing the Desorption Efficiency and Enabling Preconcentration of Brominated Pollutants for Mass Spectrometry Detection
{{output}}
Covalent organic frameworks (COFs) exhibit exceptional adsorption capacity but suffer from challenging desorption. In this study, a bromine-functionalized magnetic COF composite (Fe3O4@COF-Br) was synthesized via bromodimethylsulfonium bromide-mediated bromina... ...
