A lipophilic dye consisting of a (1E,3E,5E)-1,6-diphenyl-1,3,5-hexatriene (DPH) fluorophore attached to a phosphate diester was prepared, and its fluorescence behavior in different solvent systems and in a liposomal membrane bilayer was examined. The key step in the synthesis of the functionalized end of the dye is a Sonogashira coupling of protected iodophenol with propargyl alcohol; the remaining phenyl ring and double bonds of the all-trans polyene core arise from a Wittig reaction with trans-cinnamaldehyde. Like DPH itself, the emission intensity of its phosphorylated derivative is quenched in polar media.
