A dinuclear alkynylplatinum(II) pyridinedicarboxamide: conformational change-induced switching of emission properties

The synthesis and characterisation of a dinuclear pyridinedicarbox-amide-platinum(II) complex exhibiting tunable optical properties based on metal-metal interaction are reported. Conformational change-induced switching between metal-to-ligand charge-transfer and metal-metal-to-ligand charge-transfer emission properties by the influence of methanol was demonstrated.
