Sr. Kim et al., THE CHARACTERISTICS OF METALLOPHTHALOCYANINE MONOLAYER, MULTILAYER AND APPLICATION TO THE GAS SENSOR FOR NO2, Synthetic metals, 71(1-3), 1995, pp. 2293-2294
The preparation of Langmuir-Blodgett(LB) films of metallophthalocyanin
es(MPcs) with symmetric octa(2-ethylhexyloxy) side chain and their pos
sible use in gas sensing device were examined. Complexed central metal
ion, which include copper, lead, platinum, cobalt and dihydrogen was
varied and 2-ethylhexyl chains were substituted at both 2- and 3-posit
ion of each binge ring in the phthalocyanine compound. Mono- and multi
layer LB films were transferred to a 6 MHz quartz crystal microbalance
(QCM) by vertical dipping method. The interaction or responses of film
coated QCM to NO2 have been tested, and after the heat treatment, the
good recovery efficiencies were achieved for repeated use.
