摘要

采用二（磷）盐[DPEPhosMe2]I2与二（磷）盐[DPEPhosMe2]I2反应合成了四碘锰酸双磷（II） [DPEPhosMe2]MnI4。在室温下，[DPEPhosMe2]MnI4多晶样品呈现亮绿色磷光（λmax = 546 nm），量子产率为77%。磷光衰减寿命为45 μs，对于Mn2+为中心的磷光来说，这是相当短的。

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 (λ_max = 546 nm) with a quantum yield of 77%. The phosphorescence decay lifetime is 45 μs, which is rather short for Mn²⁺-centered phosphorescence.
