제목 N,N-dioctadecyl-p-nitrophenylaniline LB막의 분자배향과 비선형광학 특성에 관한 연구
초록 Optical and spectroscopic properties of Langmuir-Blodgett(LB) films of N,N-dioctadecyl-p-nitrophenylaniline (DONPA) mixed with cadmium arachidate(CdA) were measured to characterize orientation of molecular and structural effect on SHG intensity of the films. The LB films were fabricated with various molar ratios of DONPA and CdA to investigated the orientation effect of DONPA on CdA in the mixed LB films. The molecular orientations of molecules in LB films were examined by using the polarized transmission and reflection-absorption FT-IR and the UV-visible absorption technique. The second harmonic generation (SHG) intensities of LB films were measured. Chromophore of DONPA formed the J-aggregates. The DONPA in 1:1 mixture DONPA:CdA LB films oriented with an angle of 61*3 * from surface normal, and with parallel orientation to the dipping direction .
