A novel class of chiral luminescent square-planar platinum complexes with a π-bonded chiral thioquinonoid ligand is described. Remarkably the presence of this chiral organometallic ligand controls the aggregation of this square planar luminophor and imposes a homo- or hetero-chiral arrangement at the supramolecular level, displaying non-covalent Pt-Pt and π-π interactions. Interestingly these complexes are highly luminescent in the crystalline state and their photophysical properties can be traced to their aggregation in the solid state. A TD-DFT calculation is obtained to rationalize this unique behavior.
描述了一类新型的具有π键合手性硫代醌类配体的手性发光平面正方形铂配合物。值得注意的是，这种手性有机金属配体的存在控制了这种平面正方形发光体的聚集，并在超分子水平上形成了同手性或异手性排列，显示出非共价的Pt-Pt和π-π相互作用。有趣的是，这些配合物在晶体状态下具有高发光性，其光物理性质可追溯到它们在固态中的聚集。通过TD-DFT计算来解释这种独特行为。
