 Multiple films of copper phthalocyanine derivative embedded SnO2 ultrafine particles were studied. The results indicated that there is interaction between CuPc and SnO2, and structure of CuPc is destroyed to some extent. Gas-sensitivity measurements show that conductance of LB films after embedding increases about one order of magnitude, stability of gas-sensing also increases.
