We designed and synthesized binaphthyl-containing polymers for gas-phase detection of dimethyl methylphosphonate (DMMP), a nerve agent simulant, using quartz crystal microbalance (QCM). Resonance frequency of QCM is shifted due to the adsorption and desorption of a compound at the surface of the modified quartz crystal electrode. We envisioned that the nonplanar structure of binapthyls would render the polymers microporous, which induces better adsorption of DMMP molecules. Further, we incorporated hexafluoro-isopropylalcohol (HFIP) groups to increase the binding capacity of DMMP. We prepared several polymers with binaphtyl groups and HFIPs, and found that frequency shifts were linear to the concentrations of DMMP in the range of 10-60 ppm. |
