Abstract

We describe a novel oxygen polarization sensor based on a single molecule that changes the observed anisotropy of its emission with variation of the oxygen concentration. The approach is demonstrated both in solution and in solid films. A simple mathematical description of the sensor is included and experimentally verified. The technique demonstrated here creates opportunity for development of a new class of polarization-based dyes and sensors.
