摘要

A novel class of chiral luminescent square-planar platinum complexes with a pi-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 pi-pi 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.
