초록

It is well known that the metallo-phthalocyanines(MPcs) are sensitive to toxic gaseous molecules, such as NO$_2$, NO, SO$_2$. MPcs are thermally, optica1ly, mechanically and chemically stable. Therefore, it is interesting to prepare phthalocyanine LB films containing tin as a chemical sensor for NO$_2$ and SO$_2$ gas and test their sensitivity to these toxic gases. Frist, in this study, ultra thin films of Octa-dodecyloxy tin-phthalocyanine were prepared on various substrates by LB technique. Langmuir-Blodgett(LB) technique is one of the ways of fabricating organic thin films. It has the advantage to control the alignment and orientation of the molecules in the films. $\pi$-A isotherm and transfer ratio of tin-phthalocyanine derivative. UV-VIS. spectroscopy were investigated. Also intrinsic current-voltage(1-V) characteristics of these films was investigated.
