Fluorescence Quenching of a Europium Coordination Compound for the Detection of

The coordination compound Eu(DAF)(2)(NO3)(3) (1, DAF = 4,5-diazafluorene), which shows strong red fluorescence, has been synthesized and characterized. The luminescence-quenching effect of 1 has been applied to the detection of water in CH3CN. For the first time, the response mechanism has been unco
