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

Abstract

Arylisocyanide complexes based on earth-abundant Group 6 d6 metals are interesting alternatives to photoactive complexes made from precious metals such as RuII , ReI , OsII , or IrIII . 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 Cr0 , Mo0 , and W0 arylisocyanide complexes have great potential for applications in luminescent devices, photoredox catalysis, and dye-sensitized solar cells.
