摘要:

在三-(2,4-二特戊基苯氧基)-一-(8-喹啉氧基)酞菁铜中掺杂SnO2超微粒子复合成膜,发现SnO2与酞菁铜分子之间有一定的相互作用,对酞菁铜分子的结构有一定的破坏; 气敏性研究表明掺杂后导电率提高一个数量级,稳定性提高.

关键词: 酞菁铜, SnO2, LB膜, 气敏性

Abstract:

 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.
