Usage

General Description

2,2':5',2''-Terthiophene, 3',4'-dinitro- is a chemical compound that belongs to the class of thiophenes, which are five-membered aromatic heterocycles containing sulfur. It has a molecular formula of C8H4N2O4S3 and a molecular weight of 288.31 g/mol. 2,2':5',2''-Terthiophene, 3',4'-dinitro- is a derivative of terthiophene, which is a widely studied building block for organic electronics due to its unique electronic properties. The introduction of dinitro substituents at the 3' and 4' positions on the terthiophene ring alters its electronic properties and can be used for various applications in organic electronics and materials science.

Pushing fullerene absorption into the near-IR region by conjugately fusing oligothiophenes

Fusing two in one: The π-electron systems of fullerene and an oligothiophene were conjugately fused by an open-cage process. This led to novel fullerene-oligothiophene chromophores with significantly enhanced light-absorbing capability, which covers a wid

Anionic N-heterocyclic carbenes derived from sydnone imines such as molsidomine. Trapping reactions with selenium, palladium, and gold

The sydnone imines Molsidomine and 5-(benzoylimino)-3-(2-methoxyphenyl)-1,2,3-oxadiazolium-2-ide gave anionic N-heterocyclic carbenes on deprotonation at C4 which were trapped as methylated selenium adducts, gold complexes (X-ray analysis) as well as palladium complexes (X-ray analysis). The 13C NMR resonance frequencies of the carbene carbon atom are extremely shifted upfield and appear at δ = 142.1 ppm (Molsidomine carbene) and δ = 159.8 ppm (sydnone imine carbene). The Pd complexes were applied as catalysts in Suzuki-Miyaura and Sonogashira-Hagihara cross-coupling reactions.
