Abstract

Series selective and sensitive films were designed and fabricated for sensing volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs). The molecular recognition host reagents were designed and synthesized for optimum binding or organic vapors. Sensing films were fabricated onto a surface acoustic wave (SAW) transducer surface through molecular self-assembly and covalent immobilization. The selectivity and sensitivity of the film are based on host-guest interaction, between the host reagent (cyclodextrins) and gas phase species. The self- assembled film containing cyclodextrins can detect certain organic vapors at parts per billion concentrations.
