2D luminescent metal–organic framework: efficient and highly selective detection of 2,4,6-trinitrophenol at the ppb level

Abstract

A 2D Cd-MOF (<bold>CUST-531</bold>) was reported as a sensor to detect <bold>TNP</bold> with high sensitivity and selectivity. The quenching mechanism is the turn-off response of the fluorescence signal, which can be observed by the naked eye under UV-vis lamp irradiation.
