Abstract

In this research, We fabricated Langmuir-Blodgett(LB) ultra-thin films with (N-docosyl quinolinium)- TCNQ(1:2) complex. The characteristics ${\pi}$-A isotherms were studied to find optimum conditions of deposition by varing temperature of subphase, compression speed of barrier and amount of spreading solution. Film formation was verified by measuring transfer ratio, maximum absorption of UV-vis spectra, capacitance and ellipsometry. From the results, it was concluded that the LB film formed well with molecular oder was fabricated.

본 연구에서는 (N-docosyl quinolinium)-TCNQ (1:2) 착물의 LB초박막을 제작하였다. LB막의 누적을 위한 최적조건을 구하기 위하여 subphase 온도, barrier 압축속도 및 분산량을 변화시키면서 표면압-면적(${\pi}$-A) 등온선 특성을 측정하였다. 그리고 전이비, UV-vis의 최대 흡광도, 정전용량 및 두께를 측정하여 LB막의 누적상태를 확인하였다. 그 결과 분자수준으로 잘 제어된 양호한 LB막이 제작되었음을 알 수 있었다..
