5,6-Di-2-thienyl-2,3-dihydropyrazine

5,6-Di-2-thienyl-2,3-dihydro­pyrazine

In the title compound, C(12)H(10)N(2)S(2), which was synthesized by the reaction of 2,2'-thenil and ethyl-enediamine, the dihedral angle between the two thio-phene rings is 66.33 (9)°. In the crystal structure, inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into infinite chains along the b axis and weak C-H⋯π inter-actions may further stabilize the structure.

Synthesis and anticancer activity of di(3-thienyl)methanol and di(3-thienyl)methane.

Di(3-thienyl)methanol (2) and di(3-thienyl)methane (3) have been synthesized and screened against the T98G (brain cancer) cell line. Treatment induced cell death (MTT and macro-colony assay), growth inhibition, cytogenetic damage (micronuclei formation), were studied as cellular response parameters. Treatment with the compounds enhanced growth inhibition and cell death in a concentration depend...

Electrosynthesis and Characterization of Polypyrrole in the Presence of 2,5-di-(2-thienyl)-Pyrrole (SNS)

A novel calamitic mesophase semiconductor with the fastest mobility of charged carriers: 1,4-di(5'-octyl-2'-thienyl)benzene.

The carrier mobility of highly ordered lamellar mesophases was evaluated by a Time-of-Flight (TOF) method for mesogenic 1,4-di(5'-octyl-2'-thienyl)benzene (8-TPT-8) to reveal the fastest drift mobility (0.1 cm(2) V(-1) s(-1) for the lowest temperature mesophase) in calamitic liquid crystals reported to date.

D-D-π-A organic dyes containing 4,4'-di(2-thienyl)triphenylamine moiety for efficient dye-sensitized solar cells.

Dye-sensitized solar cells (DSSCs) are currently under intense academic and industrial investigations, because of their environmentally-friendly, efficient, and low-cost features. The photosensitizer plays a key role in determining DSSCs' performance. The 4,4'-di(2-thienyl)triphenylamine moiety, included in dye TTC102, has been demonstrated before as a novel and efficient electron donor fragmen...
