The characteristics of metal substituted phthalocyanine mono-, multilayer and application to the gas sensor for toxic gases

Summary form only given. The preparation of Langmuir-Blodgett(LB) films of metal substituted phthalocyanines and their possible use in gas sensing device were examined. Complexed central metal ion, which include copper, lead, platinum, cobalt and hydrogen was varied and 2-ethylhexyl chains were substituted at both 2- and 3- position of each bingo ring in the phthalocyanine compound. Mono- and multilayer LB films were transferred to a 9-MHz quartz crystal microbalance (QCM) by vertical dipping method. The interaction or responses of film coated QCM to toxic gases have been tested. For this study, various mixed films were prepared and the characterizations of the films on substrate was performed.
