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.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Photoinduced copper-catalyzed C–N coupling with trifluoromethylated arenes

Nature Communications, 2023
Selective defluorinative functionalization of trifluoromethyl group (–CF3) is an attractive synthetic route to the pharmaceutically privileged fluorine-containing moiety. Herein, we report a strategy based on photoexcited copper catalysis to activate the

Regioselective oxidation of heterocyclic aromatic hydrocarbons catalyzed by cytochrome P450: A case study of carbazole

Ecotoxicology and Environmental Safety, 2023
Recently there are increasing interests in accurately evaluating the health effects of heterocyclic PAHs. However, the activation mechanism and possible metabolites of heterocyclic PAHs catalyzed by human CYP1A1 is still elusive to a great extent.

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...
