The chromium(III) complex Cr(ppy)3, a structural analog of the green phosphorescent iridium(III) complex Ir(ppy)3 (from a metal-to-ligand charge-transfer state), emits even in solution at room temperature from a weakly distorted...

Steric protection strongly reduces phosphorescence quenching of excited molecular rubies by oxygen. The most bulky ligand enables photoluminescence quantum yields up to 5.1% and lifetimes up to 518 µs in air-saturated acetonitrile.
