Chromium(0), Molybdenum(0), and Tungsten(0) Isocyanide Complexes as Luminophores and Photosensitizers with Long-Lived Excited States.

Arylisocyanide complexes based on earth-abundant Group 6 d(6) metals are interesting alternatives to photoactive complexes made from precious metals such as Ru(II) , Re(I) , Os(II) , or Ir(III) . Some of these complexes have long-lived (3) MLCT excited states that exhibit luminescence with good quantum yields as well as nano- to microsecond lifetimes, and they are very strongly reducing. Recent studies have demonstrated that Cr(0) , Mo(0) , and W(0) arylisocyanide complexes have great potential for applications in luminescent devices, photoredox catalysis, and dye-sensitized solar cells.
