Abstract
A phthalocyanine derivative: 2,9,16,23-tetra-tert-butyl-29H,31H-copper(II) phthalocyanine (CuttbPc) was used as an optical gas sensor based on Langmuir-Blodgett (LB) films. Surface pressure-area per molecule (π–A) isotherms and Brewster Angle Microscopy (BAM) will show the process of the monolayer formation at the air-water interface. The responses of the thin films to various volatile organic compounds (VOCs) were recorded by UV-Vis absorption spectra and the morphological characterization was performed by Atomic Force Microscopy (AFM). The experimental results indicate that highly-ordered and uniform films can be prepared at about 33mN/m with the transfer ratio of 0.7. The results also demonstrated that CuttbPc LB films are promising to be applied into optical gas sensors for VOCs detection and recognition.
