Аннотация:Symmetrical Pt complexes with 8-oxyquinoline and 2-mitil-8-oxquinoline derivatives have been synthesized and purified by vacuum distillation to the purity better that 99.998 wt%. The OLED structures with individual Pt complexes as an emitting agents and as a dopant in CBP matrix have been made by vacuum sputtering. The properties of the OLED structures have been investigated.
