These compounds benefit from the square-planar geometry of platinum(II) and the rigidity of the tetradentate ligand. Cyclometallated ligands are particularly appealing since they are thermally stable and display a high ligand field splitting which favors efficient emission. The photophysical properties of these complexes can be tuned by structural modifications, introduction of substituents or control of the intermolecular interactions. Several of the studied compounds have been successfully tested for electroluminescent devices. An overview of the advances reported in this field for the last five years is presented in this work.
