Multistep synthesis and electrochemical characterization of an Os complex-modified redox hydrogel exhibiting a redox potential ≈+30 mV (vs. Ag/AgCl 3 m KCl) is demonstrated. The careful selection of bipyridine-based ligands bearing N,N-dimethylamino moieties and an amino-linker for the covalent attachment to the polymer backbone ensures the formation of a stable redox polymer with an envisaged redox potential close to 0 V. Most importantly, the formation of an octahedral N6-coordination sphere around the Os central atoms provides improved stability concomitantly with the low formal potential, a low reorganization energy during the Os3+/2+ redox conversion and a negligible impact on oxygen reduction. By wiring a variety of enzymes such as pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase, flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenase and the FAD-dependent dehydrogenase domain of cellobiose dehydrogenase, low-potential glucose biosensors could be obtained with negligible co-oxidation of common interfering compounds such as uric acid or ascorbic acid. In combination with a bilirubin oxidase-based biocathode, enzymatic biofuel cells with open-circuit voltages of up to 0.54 V were obtained.

This invention pertains to light emitting materials comprising novel ortho-metalated transition metal complexes [C?N]2ML, comprising chelate monoionic ligands (L), also called ancillary ligands. It has been surprisingly found that when the ancillary ligand comprises a substituted aromatic ring bearing a substituent possessing adequate electron-donating properties, said ligand (L) advantageously participates in the emission process, significantly shifting emission towards higher energies (blue-shift) and enabling appreciable improvement of the emission efficiency of complexes [C?N]2ML. Still objects of the invention are the use of said light emitting materials and organic light emitting device comprising said light emitting material.
