Abstract
The LB films of four hemicyanine salts with rare earth complex anions were prepared. From second-harmonic generation experiments, the second -order molecular hyperpolarizability beta was evaluated to be about 2X 10(-27) e.s.u. Enhanced second-order nonlinearity compared with the he micyanine bromide was discussed according to the crystal structure of a model complex. The results of UV -Vis, IR and low angle X-ray diffra ction for the LB films are also reported.
