Highly luminescent metal complexes can be designed around Ru(II), Os(II), Ir(III), and Re(I) with {alpha}diimine ligands such as 1,10-phenanthroline and 2,2{prime}-bipyridine. Complexes can absorb intensely and have luminescence quantum yields in excess of 0.5 and lifetimes of 5-100 {mu}s in room temperature fluid solutions. These properties make them ideal for luminescence sensors and molecular probes for use in fiber optic based sensors. The chemical and spectroscopic characteristics that yield stable, highly luminescent long lived complexes are largely understood. This allows the rational design of new molecules with specially tailored luminescence or binding properties. We describe the primary considerations that go into designing new systems. We also describe applications to luminescence oxygen sensors and probes of macromolecular binding with micelles and cyclodextrins.
