Description
Summary:This communication reports the formation of complex Langmuir monolayer at the air-water interface with the water-soluble -trimethyl ammonium bromide (CTAB) molecules when interacted with the stearic acid (SA) molecules. The reaction kinetics of the formation of the CTAB-SA complex was monitored by observing the surface pressure versus time graph. Multilayered LB films of this complex doped with congo red was successfully formed onto a quartz substrate. UV-Vis absorption and steady state fluorescence spectroscopic characteristics of this doped LB films confirms the successful incorporation of congo red molecules in to the CTAB-SA complex films.
