Constructing imine and amine-based hydrogen-bonded organic frameworks in aqueous media and selective CO2 adsorption

In situ generated dimethylamine constructs a robust hydrogen-bonded organic framework for selective fluorescence detection

“…1 HOFs represent a class of crystalline framework structures formed by intermolecular hydrogen bonds between organic or metal-containing molecules, assembled through the synergistic action of other non-covalent interactions such as π-π stacking. 2 Current research efforts focus on these aspects, propelling advancements in various fields including dye adsorption and degradation, 3,4 proton conduction, 5,6 catalysis, 7,8 luminescence phenomena, 9,10 anti-counterfeiting and sensing technologies, [11][12][13][14][15][16] biological applications, [17][18][19][20] gas separation processes, 21,22 enantiomer resolution and separation of aromatic compounds, 23 etc. Since the beginning of the 21st century, MOFs have experienced explosive development, while COFs have recently entered a stage of rapid growth.…”
