Spectroscopy and photophysics of tungsten arylisocyanides

We report the structures and spectroscopic properties of third generation tungsten(0) arylisocyanides. These complexes exhibit very intense absorptions and strikingly bright emissions in the visible region. The lowest electronic excited states, some with microsecond lifetimes, are very strong reductants. The complexes also have large two-photon absorption cross sections (> 1000 GMs), enabling the study of near-IR-triggered photoredox chem.
