Circularly polarized luminescence (CPL) activity switched by PtPt interaction is disclosed in two couples of dinuclear Pt(ii) complex enantiomers. Upon varying the length of the bridging ligand, intramolecular metal-metal interaction manipulation is achieved as evidenced from crystal structures. Complex (-)-1 exhibiting strong PtPt interaction displays red phosphorescence with a maximum peak at 638 nm, while complex (-)-2 exhibiting weak PtPt interaction displays green phosphorescence with a maximum peak at 530 nm. The observed CPL was opposite in sign for the two complexes. TD-DFT simulations further confirmed the influence of the PtPt distance on the difference in the electronic optical activities. |
