, p. 4035 - 4038 (2015)
A one-pot Rh(I)-catalyzed synthesis of 9-H carbazoles via C-N bond cleavage by activation of aldehyde C-H bonds is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible decarbonylation mechanism.

Three deep blue thermally activated delayed fluorescence (TADF) molecules are designed by connecting three different sterically hindered electron-donating groups with 2,6-diphenylpyrimidine acceptors. The rigid structures based on carbazole derivatives en

Treatment of 1-aminobiphenyl and diphenylamine with catalytic amount of Pt/C in hydrothermal water (250 °C, 4 MPa) affords 9H-carbazole in good yield. In this catalytic cycle, water works as reoxidizing reagent for platinum catalyst. Copyright
One-pot synthesis of carbazoles from cyclohexanones and arylhydrazine hydrochlorides under metal-free conditions
Xiao, Fuhong,Liao, Yunfeng,Wu, Mingyue,Deng, Guo-Jun
, p. 3277 - 3280 (2012)
One-pot synthesis of carbazoles from cyclohexanones and arylhydrazine hydrochlorides is disclosed. Various substituted carbazoles were obtained in moderate to good yields via a sequence of condensation, cyclization and dehydrogenation under metal free conditions using molecular oxygen as an oxidant.

An unforeseen twist in a seemingly trivial Bischler-Napieralski reaction led to the selective formation of an unexpected carbazole product. The reaction proved to be general, providing access to a range of diversely substituted carbazoles from readily available substrates. Judicious variation of substituents revealed a complex cascade mechanism comprising no less than 10 elementary steps, that could be diverted in multiple ways toward various other carbazole derivatives.

In this contribution, a novel bipolar host material, namely CzTrz, consisting of a phenylcarbazole for hole transport and a diphenyltriazine for electron transport, was synthesized and investigated. Besides, a carbazole-based unipolar host BCz2 was designed as a reference. Both CzTrz and BCz2 display good thermal stability, high triplet energy level (ET) and suitable frontier orbital levels. Green PhOLEDs hosted by CzTrz and BCz2 show turn-on voltage (Von) of 3.5 and 3.8 V, maximum luminance (Lmax) of 30,280 and 35,050 cd m?2, and maximum external quantum efficiency (EQEmax) of 15.49 and 11.84%, respectively. Remarkably, the CzTrz-based device reveals an extremely low efficiency roll-off at the high luminance, for example, 15.35% at 1000 cd m?2 and 13.85% at 5000 cd m?2, corresponding to merely 0.9% and 10.6% roll-off percentage, which is among the best results ever reported as green bipolar hosts.

Concatenating Suzuki Arylation and Buchwald–Hartwig Amination by A Sequentially Pd-Catalyzed One-Pot Process—Consecutive Three-Component Synthesis of C,N-Diarylated Heterocycles
Mayer, Laura,Kohlbecher, Regina,Müller, Thomas J. J.
supporting information, p. 15130 - 15134 (2020/10/20)
The concatenation of Suzuki coupling and Buchwald-Hartwig amination in a consecutive multicomponent reaction opens a concise, modular and efficient one-pot approach to diversely functionalized heterocycles, as exemplified for 3,10-diaryl 10H-phenothiazines, 3,9-diaryl 9H-carbazoles, and 1,5-diaryl 1H-indoles, in high yields starting from simple staring materials. Moreover, this one-pot reaction is a sequentially palladium-catalyzed process that does not require additional catalyst loading after the first coupling step.
