摘要：
Metal-mediated self-assembly of isocyanides and methyl 4-aminopyrimidine-5-carboxylate leads to luminescent Pd-II and Pt-II complexes featuring C,N-cyclometalated acyclic diaminocarbene (ADC) ligands. The solid-state luminescent properties of these diaminocarbene derivatives are attributed to their triplet-state metal/metal-to-ligand charge-transfer ((MMLCT)-M-3) nature, which is driven by attractive intermolecular M<middle dot><middle dot><middle dot>M interactions further reinforced by the intramolecular pi-pi interactions even in the structure of the Pd compound, which is the first Pd-ADC phosphor reported.
