Paper Abstract

Second Harmonic Generation of a new hemicyanine dye was measured. The LB-films were either pure dye-monolayers or mixed dye-arachidic acid films. An increase of SHG was observed with a decrease in dye concentration in the mixed films. For multilayer films a subquadratic increase in SH-intensity with the number of dye layers was observed. Aggregation and orientation of the dye molecule in the monolayers and films were studied by reflection and absorption spectroscopy.
