High-efficiency white organic light-emitting diodes (WOLEDs) were fabricated with two emissive layers and an exciton blocking layer (EBL) was sandwiched between two phosphorescent dyes, bis(3,5-difluoro-2-(2-pyridyl)phenyl-(2-carboxypyridyl) iridium III (FIrpic) as the blue emission and iridium(III) bis(5-acetyl-2-phenylpyridinato-N,C2′) acetylacetonate ((acppy)2Ir(acac)) as the red emission. This EBL effectively prevented a triple–triple energy transfer between the two phosphorescent emissive layers with blue and red emission. The white device showed Commission Internationale De L'Eclairage (CIEx,y) coordinates of (0.33, 0.42) at 22400 cd/m2, a maximum luminance of 27300 cd/m2 at 13.2 V, and a maximum luminous efficiency of 26.9 cd/A.

A novel platinum complex FBNNND shows rare non-aggregation in solid state and hence the same emission color both in solution and in solid state, which is drastically different from that of FPtOPhND, a classical platinum complex.

Two new homoleptic platinum(ii) complexes are reported that feature aryl-appended 5-(2-pyridyl)-1,2,4-triazole chelates acting as N^N− ligating ions, PtL12 and PtL22. They have been used to prepare high-efficiency OLEDs, in which unimolecular and bimolecular excited states contribute green and red emission respectively.
