Paper Abstract

We have studied the absorption of volatile organic compounds (VOCs) and vapochromic characterization by a colorimetric array based on metalloporphyrins and Pt complexes: ZnTPP, CuTPP, and [Pt(Me2bizmpy)Cl]Cl (TPP=tetraphenylporphrins; Me2bzimpy=2,6-bis(N-methylbenzimidazol-2-yl)pyridine). The array was exposed to pyridine, tetrahydrofuran, ethyl acetate, methanol and acetonitrile. The experimental results demonstrate that the Pt complexes are sensitive to methanol and acetonitrile, while ZnTPP and CuTPP present an obvious response to pyridine, tetrahydrofuran and ethyl acetate. The response behaviors are reversible and rapid within seconds. The changes of Ultra Violet Visible (UV-visible) absorption spectrums of ZnTPP and CuTPP LB films before and after exposure upon the VOCs are also discussed. In addition, the differences of absorption spectrum of Pt complexes dissolved in several solvents are mentioned. The results show that [Pt(Me2bizmpy)Cl]Cl, CuTPP and ZnTPP exhibit reversible changes of action with VOCs, and they show promising future to be used in Smell-Seeing Electronic Nose to identify VOCs.
