A unique delaminated MoS4/OS-LEuH composite exhibiting turn- on luminescence sensing for detection of water in formamide

We demonstrate a novel example of a delaminated MoS4/OS-LEuH composite (LEuH is layered europium hydroxide, OS is 1-octane sulfonate), which exhibits quenched luminescence in formamide and highly enhanced red emission in the water-present case. The turn-on luminescence sensing capability of the material is promising for feasible detection of a trace amount of water in formamide (FM) and N, N-dimethylformamide (DMF).
