Synthesis of Carbazoles and Derivatives from Allenes
, 2022 Carbazole heterocycles are ubiquitous in nature, and frequent motifs in materials such as polymers, dyes and light emitted devices. Among the wide variety of strategies towards the synthesis of carbazoles, the allene-based methodology represents one of

Advanced Functional Materials, EarlyView.A triplet‐blocking layer controls triplet exciton dynamics in blue upconversion OLEDs. The layer keeps charge transfer (CT)‐generated triplet excitons inside the triplet‐triplet annihilation (TTA) host, suppresses anode‐side interfacial quenching, and increases the steady‐state triplet population.

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

3-(Trimethylsilylethynyl)carbazole
Acta Crystallographica Section E Structure Reports Online, 2003 The title compound, [Si(CH3)3(C14H8N)] is a TMS-protected mono-alkyne. It is used as a model species for platinum σ-acetylide compounds of which it is a precursor. Such compounds are of interest due to the extended π-conjugation through the hetero-aromatic linker unit in the backbone.

9-[3-(Carbazol-9-yl)-5-methylphenyl]carbazole [PDF]
Acta Crystallographica Section E Structure Reports Online, 2013 The title compound, C31H22N2, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The mol-ecules have slightly different conformations, the dihedral angles between the central phenyl ring and the carbazolyl groups being 56.29 (4) and 59.57 (4)° in one mol-ecule and 48.71 (4) and 65.47 (4)° in the other.
