New Tetraiodomanganate(II) with Highly Efficient Short-Lived Phosphorescence
Biphosphonium tetraiodomanganate(II) [DPEPhosMe2]MnI4 has been synthesized by the reaction of MnI2 with bis(phosphonium) salt [DPEPhosMe2]I2, which is prepared by the alkylation of DPEPhos with methyl iodide. At ambient temperature, polycrystalline samples of [DPEPhosMe2]MnI4 exhibit bright green phosphorescence (λmax = 546 nm) with a quantum yield of 77%. The phosphorescence decay lifetime is 45 μs, which is rather short for Mn2+-centered phosphorescence.
