Luminescent metal complexes. Part 5. Luminescence properties of ring-substituted 1,10-phenanthroline tris-complexes of ruthenium(II)

Abstract

The absorption characteristics, emission spectra, luminescent quantum yields, and lifetimes are reported for 24 ruthenium(II) tris-1,10-phenanthroline complexes in EtOH–MeOH solution. Quantum yields fall between 0.019 and 0.403, the highest values being recorded for complexes substituted at the 4,7-sites with aryl groups. Incorporation of these derivatives into poly(vinyl chloride) film raises the quantum yields leading to values ranging from 0.40 to 0.75.
