“…8,9 The utilization of uorescence sensing has made signicant progress in recent years for pollutant monitoring and the advancement of portable sensing equipment, owing to its exceptional sensitivity, cost-effectiveness, and prompt response. [10][11][12] With the advantages of tunable structure, [13][14][15] large surface area, 16,17 and abundant active sites, 18,19 luminescent metal-organic frameworks (LMOFs) 20 are widely used in uorescence detection of diverse pollutants. [21][22][23][24][25] However, the majority of uorescence sensing technology based on LMOFs primarily relies on single-parameter indicators to detect 2,4-DNP.…”
