Investigation of gas-sensing properties of copper phthalocyanine films

In this work, the sensor response of thin films of octasubstituted copper phthalocyanine derivative (CuPcR8) with bulky substituents on R = –N(SO2C6H5–CH3)CH2(CH2)8CH3 to the vapour of benzene, chloroform, ethanol and butanol were investigated by surface plasmon resonance technique. The application and some advantages of total internal reflection ellipsometry method for determination of the organic vapours are also demonstrated.
