Abstract
n-Octadecyl 4-(4'-nitrophenylazo)-1-naphthyl ether, ONNE, was synthesi zed and the optical characteristics of ONNE was studied. Noncentrosymm etric Z-type Langmuir-Bodgett (LB) films of ONNE were prepared and the second harmonic generation, SHG, intensity of the films were measured . The structural characteristics of floating monolayer and LB film of ONNE were discussed with the pi - A isotherm, UV - visible absorption spectroscopy and ellipsometry. The polarized UV - visible absorption s pectroscopy and SHG intensity suggest molecular orientation in LB film .
