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

摘要

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 3MLCT 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.
