Abstract
The present invention relates to polymeric luminophores which contain ruthenium, osmium, and rhenium complexes covalently attached to polymer matrices. The polymeric luminophores are capable of having their luminescence quenched by molecular oxygen and may be coated on optical fibers to form sensing elements to detect oxygen in gases and fluids.
