Rational molecular design of novel host material combing intra- and intermolecular charge transfers for efficient solution-processed organic light-emitting diodes

Two novel D-σ-A molecules bearing 2,4,6-diphenyl-1,3,5-triazine (TRZ) units as electron-accepting segment and 1,3-di (9H-carbazol-9-yl)benzene (mCP) or 9'-(4-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenoxy)phenyl)-9′H-9,3':6′,9″-tercarbazole (TCz) as electron

Dendron engineering in self-host blue iridium dendrimers towards low-voltage-driving and power-efficient nondoped electrophosphorescent devices

Dendron engineering in self-host blue Ir dendrimers is reported to develop power-efficient nondoped electrophosphorescent devices for the first time, which can be operated at low voltage close to the theoretical limit (Eg/e: corresponding to the optical bandgap divided by the electron charge). With increasing dendron's HOMO energy levels from B-POCz to B-CzCz and B-CzTA, effective hole injection is favored to promote exciton formation, resulting in a significant reduction of driving voltage and improvement of power efficiency. Consequently, the nondoped device of B-CzTA achieves extremely low driving voltages of 2.7/3.4/4.4 V and record high power efficiencies of 30.3/24.4/16.3 lm W?1 at 1, 100 and 1000 cd m?2, respectively. We believe that this work will pave the way to the design of novel power-efficient self-host blue phosphorescent dendrimers used for energy-saving displays and solid-state lightings.

Single molecular tuning of the charge balance in blue-emitting iridium dendrimers for efficient nondoped solution-processed phosphorescent OLEDs

The single molecular tuning of charge balance has been demonstrated here by integrating a p-type dendron, an n-type dendron and a blue emissive Ir core into one dendritic platform. Compared with the commonly used physical blending, not only can the charge

N-PHENYL TRISCARBAZOLE

The present invention relates to a novel triscarbazole compound having substituent on N-phenyl, which can be represented by Formula (I). wherein R1 is selected from the group consisting of hydrogen, halogen or alkyl or alkoxy group having 1 to 20 carbon atoms wherein at least one hydrogen atom is optionally replaced by halogen; RA, RB, RC, RD and RE are any of substituents other than hydrogen wherein at least two of R1 and RA may further form a fused ring; and i, j, k, l and m are same or different at each occurrence and represent an integer from 0 to 4, with the proviso that when R1 is hydrogen, i is not 0. By introduction of the substituent on N-phenyl, the device efficiency, stability and lifetime can be increased while maintaining the solubility. These compounds can be used in various organic devices such as organic light emitting diodes, photovoltaic cells or organic semiconductor devices.
