UiO-66-NH2 as a fluorescent probe for cyanide ion (CN-) detection: assessing optimization using box-behnken design, selectivity, sensitivity, and sensing mechanism.
UiO-66-NH2 was selected as the sensing platform because its highly stable Zr6-based framework, intrinsic fluorescence, and accessible amino-functional groups provide a robust and potentially selective platform for cyanide ions (CN-) recognition without requiring additional post-synthetic modification or the incorporati...
