This study reports on the rational design of hydroxyl-functionalized covalent organic framework nanofibers (HO-COFs: PyTA-2,3-NA(OH)2 and PyTA-2,6-NA(OH)2) by a scalable solvothermal method. The resulting HO-COF is more hydrophilic than PyTA-2,6-NA(OH)2 HO-COF, which can effectively enhance sensitivity sensor toward basic ethylenediamine (EDA). fabricated nanofiber-based quartz crystal microbalance exhibits rapid sensing response distinguished selectivity EDA vapor, arising from strong hydrogen bonding interactions with NH2 groups EDA, as investigated wide variety chemical analysis techniques density functional theory calculations. presence exposed neighboring hydroxyl that face same direction in present exhibited efficient interactions. nanofiber 1.6 times higher to 100 ppm (ppm) opposite directions, low limit detection 2.9 ppm. structure has abundant active facing direction, making them favorable sites for binding molecules through bond color changed after exposure colorimetric assessment naked-eye detection.
