The first examples of phosphorescent platinum complexes bearing 2- and 3-(2-pyridyl)benzo[b]selenophenes (PyBSe) were synthesized and fully characterized. Almost identical ionization potential values (5.6 and 5.58 eV) of the solid samples of the Pt complexes were obtained by electron photoemission spectroscopy. Having slightly different molecular design, the solid solutions of the complexes emitted efficient green and red phosphorescence with absolute quantum yields of 52% (for green) and 11.6% (for red). It is demonstrated that the platinum complexes synthesized can be used as phosphorescent dopants for hybrid solution-processable OLEDs.
