Composition and method for preparing a fluorescence quenching based oxygen sensor comprising the composition

摘要

A fluorescence quenching based oxygen sensor can be prepared comprising a polystyrene polymer linked to pyrene. The fluorescence based sensor has the formula (I),
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Polystyrene-Y-R-Pyrene ;€ƒ€ƒ€ƒ€ƒ€ƒ(I)
whereinY is fluorescence quenching
and R is an aliphatic linking group having 1 to 11 carbon atoms. The sensor can be coated onto a support and integrated with an LED excitation source and fluorescence detector.
