Multi-colour uranyl emission efficiently tuned by hexacyanidometallates within hybrid coordination frameworks†
Abstract
Unique hybrid organic–inorganic coordination networks, three-dimensional [(UO2)2(OH)(4,4′-bpdo)2][M(CN)6]·nH2O (M = Co, 1; Rh, 2; Ir, 3) and layered [(UO2)2(OH)2(4,4′-bpdo)2][Pt(CN)6]·H2O (4), employing cyanide, hydroxide and 4,4′-bpdo bridges, are reported. They exhibit vibronically coupled charge transfer emission of uranyl ions, whose colour is tunable from green to orange by the implemented hexacyanidometallates.
