General Description

3-N-Octadecylthiophene is a chemical compound categorized under a group of organic substances known as thiophenes. Thiophenes are essentially sulfur-containing analogs to benzene and pyrrole and are often used in research and industry for their unique properties. 3-N-Octadecylthiophene, in particular, has the chemical formula C26H48S, suggesting it contains 26 carbon atoms, 48 hydrogen atoms, and a single sulfur atom. Its overall structure comprises an 18-carbon alkyl chain (octadecyl) attached to the 3rd position of a thiophene ring. While there's limited information on its specific uses or properties, like many thiophene derivatives, it may be potentially used in the creation of various polymer materials or in the field of organic electronics.

Check Digit Verification of cas no

The CAS Registry Mumber 104934-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,3 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104934-54:
(8*1)+(7*0)+(6*4)+(5*9)+(4*3)+(3*4)+(2*5)+(1*4)=115
115 % 10 = 5
So 104934-54-5 is a valid CAS Registry Number.

Cobalt-Catalyzed Reductive Alkylation of Heteroaryl Bromides: One-Pot Access to Alkylthiophenes, -furans, -selenophenes, and -pyrroles

Cai, Deng-Jhou,Lin, Po-Han,Liu, Ching-Yuan

supporting information, p. 5448 - 5452 (2015/08/24)

A practical and convenient Co-catalyzed alkylation method for the facile introduction of various alkyl chains into organic electronically significant heteroaryl compounds, including thiophenes, furans, selenophenes, and pyrroles, is reported. Under well-optimized reaction conditions, a wide range of alkylated heteroaryl compounds have beeen efficiently prepared in moderate to good isolated yields. Notably, 2- or 3-alkylthiophenes, which play a decisive role in polymer chemistry and organic materials, have been synthesized step-economically for the first time by this reductive-coupling methodology using inexpensive cobalt salts as catalysts. This straightforward synthetic procedure avoids the preparation of moisture-unstable organometallic reagents (RMgX or RZnX) required in conventional alkylation protocols. Various alkyl chains have been introduced into organic, electronically important heteroaryl compounds step-economically through Co-catalyzed reductive alkylation reactions. The resulting alkylheteroarenes are indispensable building blocks for polymer chemistry and π-functional organic materials.

Transition between triangular and square tiling patterns in liquid-crystalline honeycombs formed by tetrathiophene-based bolaamphiphiles

Cheng, Xiaohong,Gao, Hongfei,Tan, Xiaoping,Yang, Xueyan,Prehm, Marko,Ebert, Helgard,Tschierske, Carsten

, p. 3317 - 3331 (2013/07/26)

A series of 5,5′′′-diphenyl tetrathiophenes with polar glycerol groups at each end and two lateral flexible chains self-assemble into a series of liquid-crystalline honeycombs, formed by the π-conjugated rods which enclose polygonal prismatic cells filled by the lateral chains. With increasing chain length a discontinuous transition from triangular to square honeycombs takes place. At this transition a periodic honeycomb composed of a mixture of square and triangular cells in a ratio 1:2 was formed at low temperature, whereas at higher temperature a hexagonal columnar phase composed of triangular and randomly distributed rhombic cells, a new kind of cybotactic nematic phase, and also a cybotactic isotropic phase, both composed of square honeycomb fragments, represent the intermediate states. This provides an example of a dynamic self-assembled system where, depending on the molecular mobility, the transition between two periodic structures with different symmetry either leads to an increase of complexity, or to a chaotic regime with reduced order.

Liquid-crystalline triangle honeycomb formed by a dithiophene-based X-shaped bolaamphiphile

Cheng, Xiaohong,Dong, Xing,Wei, Guanghui,Prehm, Marko,Tschierske, Carsten

supporting information; scheme or table, p. 8014 - 8017 (2010/02/27)

Soft supramolecular triangles: The molecule shown displays a new liquid-crystalline phase formed by a periodic array of triangular cylinders. The cylinders are fused to form a honeycomb by hydrogen-bonding networks running along the vertices, and the cells are filled by molten alkyl chains. The thickness of the walls separating the compartments is equal to the width of the π-conjugated rods.
