Abstract

It is well shown that the metallophthalocyanine (MPcs) are sensitive to tonic gaseous molecules such as NO$_2$ and also chemically and thermally stable. Therefore, lots of MPcs are studied for the potential chemical sensor for NO$_2$ gas using quartz crystal microbalance(QCM) or electrical conductivity. In this study, thin films of octa(2-ethylhexyloxy) copper-phthalocyaninc ware prepared by Langmuir-Blodgett method and characterized by using UV-VIS spectrascopy and cllipsometry. Transfer condition, film characterization, and preliminary results of current-voltage(I-V) characteristics of these films exposed to NO$_2$ gas as a function of film thickness will be discusscd.
