Light-up photoluminescence sensing of a nerve agent simulant by a bis-porphyrin-salen-UO 2 complex.

A luminescent bis-porphyrin-salen-UO 2 complex, showing a significant fluorescence light-up response upon reacting with DMMP (a simulant of nerve agents), is reported. The fluorescence change of this complex by excitation at 365 nm can be clearly observed with the naked eye, and this complex was successfully employed to construct a test paper to detect nerve agents.
