The potential application of poly(1,4-phenylene diphenylvinylene), p-PDV for oxygen detection based on fluorescence quenching

Poly(1,4-phenylene diphenylvinylene), p-PDV, a photoluminescent conjugated polymer was synthesized in this study via McMurry reaction from 1,4-dibenzoylbenzene for the purpose of O2 sensing based on fluorescence quenching. The properties of this sensing polymer including fluorescence spectra, repeatability, reproducibility and the response curve were described. Results obtained from this study showed that the fluorescence intensity decreased upon exposure to O2 gas, indicating that the polymer was responsive to the presence of the O2 gas and the response was found regenerable by flushing N2 gas to the polymer solution.
