Both monoanionic dicarbene pincer chelate and dianionic azole-pyridine-carbazole cyclometalate were successfully employed in the preparation of respective bis-tridentate Ir( iii ) metal complexes ( Cz6-9 ) in moderate yields. Tuning of emission to blue was achieved by the addition of dual methoxy su...
