Thiophene is considered to be aromatic, although theoretical calculations suggest that the degree of aromaticity is less than that of benzene. The "electron pairs" on sulfur are significantly delocalized in the pi electron system. As a consequence of its aromaticity, thiophene does not exhibit the properties seen for conventional sulfides. For ...
Thieno[3,2-b]thiophene. In organic chemistry, thienothiophene is any of several compounds consisting of two fused thiophene rings. They have the molecular formula C 6 H 4 S 2. Three constitutional isomers have been synthesized: thieno[3,2-b]thiophene, thieno[2,3-b]thiophene, and thieno[3,4-b]thiophene. The other isomer features S(IV) and is ...
Poly(3-(perfluorooctyl)thiophene)s is soluble in supercritical carbon dioxide [42] [43] Oligothiophenes capped at both ends with thermally-labile alkyl esters were cast as films from solution, and then heated to remove the solublizing end groups.

Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
Thiophene-2-carboxylic acid is an organic compound with the formula SC 4 H 3 CO 2 H. It is one of two mono carboxylic acids of thiophene , the other being thiophene-3-carboxylic acid. [ 1 ] Copper(I) thiophene-2-carboxylate is a catalyst for Ullmann coupling reactions .
It is an oligomer of the heterocycle thiophene, a shorter oligomer is dithienyl, and the parent polymer is polythiophene. In the most common isomer of terthiophene, two thienyl groups are connected via their 2 positions to a central thiophene, also at the carbon atoms flanking the sulfur.
