Blue Light-Emitting Device Based on a Unidentate Organometallic Complex Containing Lithium as an Emission Layer

Pure and bright blue emission is very important for the realization of full-color organic electroluminescent devices. Here is reported the synthesis of the novel unidentate organometallic complex shown in the Figure. Analysis of its luminescence and thermal stability properties reveal that the complex is highly stable, and its electronic transition characteristics show that it could be modified for balanced charge injection and transport.
