A novel quenchometric oxygen sensor based on a low polydispersity (PDI) star polymer [Ru(bpyPS(2))(3)](PF(6))(2) (bpy = 2,2'-bipyridine, PS = polystyrene) is reported. The synthesis, characterization, photophysics, and oxygen sensing properties are examined. Combining the polystyrene support with the oxygen sensing ruthenium complex provides much higher doping levels without microcrystallization of the complex than traditional two-component sensors. The single molecule approach also avoids sensor leaching. While the polydispersity was 1.10, indicating a very tight distribution of molecular weights, sensor heterogeneity was not completely eliminated, as the luminescence decays were still multiexponentials. The likely source of this heterogeneity and possible methods for generating more homogeneous materials are discussed.
