A simple design strategy for a new class of stable, vacuum-sublimable, and strongly emissive sky-blue neutral phosphorescent Re(I) phenanthroline complexes {Re(R<sub>2sub>phen)(CO)<sub>3sub>[CNB(C<sub>6sub>F<sub>5sub>)<sub>3sub>]} is reported. These complexes show intense bluish green emission in CH<sub>2sub>Cl<sub>2sub> solution with the highest emission quantum yield and bluest emission ever reported for the neutral Re(I) diimine complexes. In the solid state, they display sky-blue emission. The electroluminescent properties of devices containing these complexes have also been investigated.
