In this work, a novel double-sided emitting organic light-emitting diode (DE-OLED) was developed, and the effect of several metal linking layers on such DE-OLEDs was investigated. To form a DE-OLED, a metal linking layer was thermally deposited between a bottom-emitting organic light-emitting diode (BE-OLED) and a top-emitting organic light-emitting diode (TE-OLED). A series of metal films of 10-nm...
Phosphorescent white organic light-emitting diodes (WOLEDs) based on single doped platinum(II) [1,3-difluoro-4,6-di(2-pyridinyl)benzene] chloride (Pt-4) emission layers were investigated in this paper. The devices exhibited electroluminescence spectra composed of bluish (λ max =480nm) and reddish (λ max =660nm) emission bands, which corresponding to monomer and excimer emission originated...
Seven compounds with pyridine as the backbone modified by carbazole moiety, bromine atom and fluorine atom were synthesized. Compounds 1, 2, 3 with bromo substitution at the 2-position and carbazole modification at the 5-position of pyridine emit not only a sharp blue singlet fluorescence but also a wide banded excimer-based orange emission. The two colors coming from a single molecule can be used...
Efficient color-stable fluorescent white organic light-emitting diodes based on a blue fluorescent host 2-(t-butyl)-9,10-di(2-naphthyl)anthracene(TBADN) co-doped with a blue guest p-di(p-N,N-diphenyl-amino-styryl)benzene(DSA-ph) and a red guest 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran(DCJTB) were reported. The luminance mechanism was explored by analyzing the...
