Synthesis and properties of a novel fluorescent surfactant
A novel kind of fluorescent surfactant by having a hydroxyl coumarin group and a sulfonate group attached to the same alkylchain has been synthesized. The determined critical micelle concentration (CMC) values and surface tensions(gamma cmc) at CMC for the fluorescent surfactant are in good agreement with the conventional surfactants. Ultraviolet absorption and fluorescence parameters of the product against the variation of the pH values are studied. The results indicate that the absorption and fluorescence intensity attribute to the interaction between the productand OH. These properties make them very promising for applications of determining the interface properties.
