1-Pyrenedecanoic acid chemisorption film as a novel oxygen sensing material

An optical oxygen sensor based on the fluorescence quenching of 1-pyrenedecanoic acid chemisorption film was developed. The I0/I100 value, where I0 and I100 represent the detected fluorescence intensities from a film exposed to 100% argon and 100% oxygen, respectively, of 1-pyrenedecanoic acid film is estimated to be 36.6. The 1-pyrenedecanoic acid chemisorption film onto alumina plate is a highly sensitive device for oxygen compared with the other oxygen sensor using pyrene compounds.
