Gold(I) pyrenyls: Excited-state consequences of carbon-gold bond formation
Partyka, David V.,Esswein, Arthur J.,Zeller, Matthias,Hunter, Allen D.,Gray, Thomas G.
, p. 3279 - 3282 (2007)
Two 1-pyrenyl derivatives of gold(I) have been prepared by base-promoted transmetalation of 1-pyreneboronic acid. Triplet-state luminescence observed from the new complexes at 77 K is assigned to a pyrene π-π* state.
