[4 + 2]-Cycloadditions to 1 '-Phenyl-Substituted 3-Vinylindoles with N-Phenylmaleimide: An Access to New [a]Anellated Carbazole Derivatives

CHIMIA, 1987
The AlCl3-catalyzed [4 + 2]-cycloaddition of T-phenyl-substituted 3-vinylindoles with N-phenylmaleimide gives rise to new anellated carbazole derivatives with a high endo-preference.

Ion Charge Compensation upon Electrochemical Doping of Redox Polymer Films with Tunable Crosslinking Density

Advanced Electronic Materials, EarlyView.
The electrochemical doping of redox homo‐ and copolymers containing triphenylamine (TPA) as redox‐active units is reported. Electrochemical crosslinking leads to films with tetraphenylbenzidine (TPB) crosslinking units. Advanced electrogravimetric tools are applied to get insights into their mixed ionic‐electronic conducting characteristics: anion ...

High‐Speed Flexible Schottky Diodes Based on Carbon Nanotubes

Advanced Electronic Materials, EarlyView.
We demonstrate a flexible Schottky diode based on carbon nanotube network thin film, and the devices are fabricated via a low‐temperature process on a PI substrate, which exhibits excellent radio‐frequency characteristics, with a high responsivity 6 A/W at zero bias, a high intrinsic cut‐off frequency reaching 153 GHz, and an extrinsic cut‐off ...

Fluorescent thiol-epoxy thermosets obtained from diglycidylether of bisphenol A and carbazole based diepoxy monomer [PDF]

, 2017
A new epoxy resin containing carbazole moieties was synthesized and added in several proportions to diglycidylether of bisphenol A (DGEBA) and trimethylolpropane tris(3-mercaptopropionate) (TTMP) formulations that were thermally cured by thiol-epoxy ...

Rational Backbone Planarization for Doping‐Resilient Polymeric Hole Transport Materials Toward Stable and Scalable Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Incorporating divinylbenzene into PTAA‐based copolymers induces backbone planarization and promotes polaron delocalization, leading to enhanced doping resilience and stabilized electronic structure. The resulting hole‐transport material, PDVB14, maintains robust performance under high dopant concentrations and prolonged device operation, offering a ...

Mechanism of the Photodecomposition of Stable Triarylmethyl Radicals. [PDF]

Angew Chem Int Ed Engl
Photolysis of luminescent chlorinated trityl radicals was studied with density functional theory and the decomposition products were isolated and characterized. It proceeds by a 5‐electron electrocyclization then a 1,8‐sigmatropic chloride shift, forming non‐emissive, less stable fluorenyl radicals.

Influence of thermal maturity on carbazole distributions in coal source rocks during compaction pyrolysis experiments

Scientific Reports
Carbazole compounds are widely used in determining the direction of petroleum migration, but the effect of thermal maturity on carbazoles is still ambiguity. In this paper, using compaction pyrolysis simulation experiments, artificial mature samples with
