PAHPV LB막의 제작 및 그 발광 특성에 관한 연구

Study on Preparation of PAHPV LB Films and Their Luminescent Characterisrics

Ultra-thin films of poly[2-[4-(9-(10-phenyl)anthracenyl)phenoxy)hexyloxy]]-1,4-phenylenevinyleylene(PAHPV) were prepare-d on the hydrophilic ITO substrate by Langmuir-Blodgett(LB) technique. ${\lambda}_{max}$ 수식 이미지 in the photoluminescence spectrum of these films was 458nm at the excitation wavelength of 365nm before thermal treatment, which comes from diphenylanthracene side chain of PAHPV. It was also confirmed with UV-Vis spectrometer that ultra-thin LB films of PAHPV precursor polymer were prepared well. After thermal treatment for conjugation of PAHPV precursor polymer, ${\lambda}_{max}$ 수식 이미지 in the photoluminescence spectrum of these films changed to 365nm, which means that the conjugation of these PAHPV films was completed.
