A solid-state fluorimetric strategy has been developed using test strips coated with Q-graphene-loaded metal-organic framework nanocomposites featuring water-triggered fluorescence turn-on. It can facilitate the real-time evaluation of trace water in organic solvents, with the level down to about 0.015% in alcohol.
