A 1,1′‐binaphthyl‐based dialdehyde, which is soluble in the fluorous phase, is synthesized. The fluorescence of this compound is greatly enhanced by 1,3‐diaminopropane (DAP) in perfluorohexane (FC‐72) but not by other amines and diamines. Thus, this compound can be used as a fluorescent sensor for the detection of the biologically important DAP at submicromolar concentrations. The selectivity and sensitivity of this fluorescent probe in this fluorous solvent are much greater than those in the common organic solvent dichloromethane.
