“…At low dopant concentration of 3 wt%, a saturated blue EL with emission maximum at 420 nm was obtained. In particular, the EL spec- [45][46][47]. As revealed by the EL spectrum, EL emission comes directly from the triplet excited states of the iridium (III) complex as the EL spectrum coincides the PL spectrum.…”

“…Aromatic amines play a central role in many areas of modern day organic chemistry, including such diverse fields as polymers, photography, medicine and materials [1][2][3]. Arylamines can be obtained either by the copper-catalyzed Ullmann condensation or palladium-catalyzed cross-coupling reactions [4][5][6][7][8][9].…”

Source of materialTo a 25-mL sidearm flask in a dry nitrogen box were added 3-bromo-benzo [de]anthracen-7-one (2.5 mmol), diphenyl-amine (2.50 mmol), Pd(CH 3 COO)2 (0.025 mmol, Pd/Br = 1 %), tri-tertbutylphosphine (0.03 mmol), and sodium fórí-butoxide (3.0 mmol). The flask was sealed with a septum and was then moved out of the nitrogen box. o-xylene (10 mL) was injected via a syringe. The reaction mixture was heated and stirred at 120 °C under nitrogen until the reaction was completed. The reaction mixture was then cooled to room temperature, Altered through a mixture of celite and silica gel pad, and washed with dichloromethane. The fíltrate was then washed with water and dried by MgSC>4. Concentration of the filtrate on a rotary evaporator followed by washing of the solid material with methanol afforded the desired crude product. The crude product was then dried at 120 °C in a vacuum and further purified by sublimation. Red crystals were obtained by sublimation at (4...6)-10" 3 Pa for 16 h.

“…The deeper the blue color (smaller CIE y-value) is, the lower the power consumption of the device is. Recently, several deep-blue OLEDs with the 1931 CIE coordinates close to the NTSC standard have been reported [7][8][9][10][11][12][13][14][15], but the OLEDs with the coordinate of y < 0.05 are still rare [16,17].…”

A new anthracene derivative 9,10-bis[3,5-di(4-tert-butylphenyl)phenyl]anthracene (BPPA) was synthesized via Suzuki coupling reaction and characterized by 1 H NMR spectrum, mass spectrum, and elemental analysis. BPPA exhibits deep-blue emission both in solution and in solid thin film. This compound has a non-planar structure that results in high thermal stability and the phenomenon of polymorphism. The non-doped device based on this material shows stable deep-blue emission with the 1931 Commission international de I'Eclairage (CIE) coordinate of (0.15, 0.05) under different applied voltages. The device exhibits the maximum external quantum efficiency of 2.2% at 14.9 mA/cm 2 with luminance of 105 cd/m 2 . organic light emitting diodes, anthracene derivative, deep-blue emission, theoretical calculations, thermal properties
