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.
摘要
描述了一种具有线性 Pt(0)-Tl(I)-Tl(I)-Pt(0)金属链的无载体四核簇合物的制备。该配合物在固态下表现出强烈的红色发射，量子产率为 73%。密度泛函理论（DFT）和含时密度泛函理论（TD-DFT）计算表明，红色发射源于铂到铊-铊电荷转移激发态。
