초록

LB 법을 이용하여 친수성 처리된 유리기판에 양친매성 스쿠아릴리움 색소의 유기초박막올 제작하였다. 기-수 계면에서의 표면압-면적 등온선 (π-A isotherm) 측정으로부터 양친매성 스쿠아릴려움 색소가 안정한 단분자막을 형성함을 알 수 있었다. 이로부터 LB 법을 이용하여 z-형 LB 막을 제작하였다. 양친매성 스쿠아릴려움 색소의 LB 악은 최대홉수파장이 684nm로서 클로로포름 용액의 경우 (637nm) 보다 현저하게 장파장쪽으로 이동되어, 이로부터 LB막에서 스쿠아릴리움 색소는 J- 회합이 형성됨을 알 수 있었다.

Ultra-thin films of amphiphilic Squarylium dye were prepared on the hydrophilic glass substrate by Langmuir-Blodgett(LB) technique. From the measurement of the surface pressure-area(π- A) isotherm at air- water interface, it was found that amphiphilic Squarylium dye can form the stable monolayers. Using the LB technique, the Z-type monolayer assembly can be obtained. The amphiphilic Squary!ium dye LB films exhibit Amax at 684nm. The absorption is significantly red-shifted from solution of amphiphilic Squary!ium dye(637nm in chloroform), suggesting that the Squarylium chromophores form J-aggregate in the LB film.
