Abstract

This paper reports the fabrication of an optical receptor for cyclohexane vapour using self-assembly monolayer (SAM) of 1-amino, 9-fluorenone compound. The SAM was built up on quartz substrate and quartz substrate-coated monolayer Langmuir-Blodgett (LB) film of arachidic acid. The UV-VIS spectroscopy technique was used to characterize the self-assembled film. It was found that the SAM on the quartz-coated LB film indicated a clearer optical absorption profile than the SAM on the quartz surface. The optical sensing characteristic of the SAM to the presence of the saturated vapour of cyclohexane indicated that the thin film features a good sensing sensitivity.
