Abstract
[PtL 6X] {X = Cl or NCS and L 6 = 5-mesityl-1,3-di(2- pyridyl)-benzene} display similar luminescence in solution but, in the solid state, the packing of the molecules is different, with short Pt⋯Pt interactions for X = NCS, leading to a red-shifted emission band. The effect has been used to generate OLEDs that emit squarely in the NIR region (855 nm).
