title: A highly efficient luminescent Pt2Tl2 chain with a short Tl(I)-Tl(I) interaction.
abstract: The preparation of an unsupported tetranuclear cluster with a linear Pt(0)-Tl(I)-Tl(I)-Pt(0) metal chain is described. The complex shows strong red emission in the solid state, having a quantum yield of 73%. Density functional theory (DFT) and time-dependent DFT calculations show that red emission originated from a platinum to thallium-thallium charge-transfer excited state.
