Platinum (II) di (2-pyrazolyl) benzene chloride analogs and uses
Synthesis of platinum(II) di(2-pyrazolyl)benzene chloride and analogs includes forming a 1,3-di-substituted benzene including two aromatic five-membered heterocycles, and reacting the 1,3-di-substituted benzene with an acidic platinum-containing solution to form a luminescent platinum(II) complex. The luminescent platinum(II) complex is capable of emitting blue and white light and can be used as an emitter in a light emitting device.
