General Description

2-Bromo-5-n-octylthiophene is a chemical compound used in the synthesis of organic electronic materials. It belongs to the family of thiophene derivatives, which are commonly employed in the production of conducting polymers and semiconducting materials. This particular compound is a brominated derivative of n-octylthiophene and possesses a bromine atom at the 2-position of the thiophene ring. This structural modification can enhance the solubility and electronic properties of the molecule, making it suitable for use in the development of organic electronic devices such as organic solar cells, light-emitting diodes, and field-effect transistors. Additionally, 2-Bromo-5-n-octylthiophene is also utilized as a building block for the functionalization and surface modification of materials in the field of organic electronics.

Synthesis of Functionalized Carbon-Sulfur [5]Helicene: Pd-Catalyzed Negishi Cross-Coupling between the β-Positions of Thiophenes

Octyl- and bromo-substituted carbon-sulfur [5]helicene was prepared in several steps starting from either thiophene or 3-bromothiophene. Pd-catalyzed Negishi cross-coupling between the β-positions of thiophenes was one of the key steps in the synthesis.

Synthesis and optical properties of soluble near-infrared arylene bisthienoimidazole dyes

Soluble, film-forming near-infrared arylene bisthienoimidazole dyes with a band gap of 1.2-1.3 eV are electrochromic and absorb strongly at the telecommunication wavelengths (1310 and 1550 nm) in the oxidized state.

Controllable morphology and self-assembly of one-dimensional luminescent crystals based on alkyl-fluoro-substituted dithienophenazines

A class of dithienophenazine derivatives, 9,10-difluoro-2,5-dialkyldithieno[3,2-a:2′,3′-c]phenazine (F-n, n = 4, 5, 6, 7 and 8), modified with various lengths of linear alkyl chains were synthesized and used as building blocks to assemble luminescent one-dimensional (1D) nano/microcrystals. It was demonstrated that the side-chain length can dramatically influence the self-assembled morphologies of the 1D nano/micromaterials. The self-assembly behaviors of F-n have been studied based on the methods of crystallization in the solution phase and solvent evaporation on a substrate. For F-4, F-6 and F-7 molecules, well-defined 1D twisted microstructures (including ribbons, fibers and bundles) were obtained. F-5 molecules can self-assemble into nearly criss-cross (orthogonal) network patterns interconnected by 1D wires. F-8 molecules with longer alkyl chains predominantly formed flattened wires. Single crystal X-ray structure studies of F-n (n = 4, 5 and 8) demonstrated that alkyl chains with different lengths result in distinctly different intermolecular interactions and molecular packing modes, which provides a reasonable explanation for the alkyl chain length-dependent assembly morphologies and emission of F-n-based nano/micromaterials. It has been demonstrated that anisotropic noncovalent interactions and mirror-symmetrical crystallization dominated the 1D assembly behaviors of this class of molecules.

ORGANIC SEMICONDUCTOR MATERIAL, ORGANIC SEMICONDUCTOR STRUCTURE AND ORGANIC SEMICONDUCTOR APPARATUS

The present invention is directed to the provision of a liquid crystalline organic semiconductor material, which is highly stable under a film forming environment and, at the same time, can easily form a film, for example, by coating. The liquid crystalline organic semiconductor material comprises: a thiophene skeleton comprising 3 to 6 thiophenes linearly connected to each other; and an identical alkyl group having 1 to 20 carbon atoms located on both sides of the thiophene skeleton, wherein acetylene skeletons each have been introduced into between the thiophene skeleton and the alkyl group, or acetylene skeletons have been introduced symmetrically into the thiophene skeleton.
