Abstract
Abstract Highly selective and sensitive quantitative detection of ofloxacin (OFX) at ultralow concentrations in aqueous media and development of new afterglow materials remains a challenge. Herein, a new 2D water‐stable lanthanide metal–organic framework (NIIC‐2‐Tb) is proposed, which exhibits high selectivity towards OFX through the luminescence quenching with the lowest detection limit (1.1 × 10 −9 M ) reported to date and a fast response within 6 s. In addition, the luminescent detection of OFX by NIIC‐2‐Tb is not affected by typical components of blood plasma and urine. The excellent sensing effect of NIIC‐2‐Tb is further utilized to prepare a composite functional sensing carrageenan hydrogel material for…
