Abstract
AbstractTo rapid and efficient detection of TNP in water (TNP=2,4,6‐trinitrophenol), a pyrenyl‐based double‐charged probe PYPN was employed. The bright orange‐red emission of PYPN was seriously quenched upon the addition of TNP. The detection limit of PYPN for TNP is 0.218 μM. In addition, PYPN shows fast response rate (5 s) to TNP, good stability, excellent selectivity and anti‐interference (pH, anion, cation and other nitro compounds). Furthermore, PYPN can be used to rapidly detect TNP in various types of water samples. The rapid and efficient detection of TNP by PYPN may due to the electron and energy transfer as well as electrostatic interactions.
