Still fluorescent upon coordination to Ru : [(η 6 ‐ p ‐cymene)Ru(dppn)(py)] 2+ (dppn=4,5,9,16‐tetraaza‐dibenzo[ a,c ]naphthacene) is highly fluorescent due to the coordinated dppn with a fluorescence quantum yield of 0.31 in acetonitrile, which is nearly the same as free dppn (0.33) and one of the highest of all luminescent Ru II complexes. The underlying mechanism may shed light on the development of Ru II arene‐based anticancer theranostic agents (see scheme).
