2-Ethylhexyl 4,6-dibromothieno [3,4-b] thiophene-2-carboxylate, its chemical structure is also. This compound is composed of several parts.
First, "2-ethylhexyl" is 2-ethylhexyl. This group is a long-chain alkyl group with a main chain of six carbon atoms and an ethyl group attached to the second carbon atom. Its structure can be regarded as a derivative of hexane. A hydrogen atom of the second carbon atom on the hexane main chain is replaced by an ethyl group, namely -CH (CH < unk > CH < unk >) CH < unk >, which mainly provides certain lipid solubility and steric resistance in the whole compound.
Furthermore, the "4,6 - dibromothieno [3,4 - b] thiophene - 2 - carboxylate" part has a thiopheno [3,4 - b] thiophene structure at the core. Thiopheno [3,4 - b] thiophene is formed by fusing two thiophene rings, and the two thiophene rings are connected in a specific way to form a unique aromatic system. At the 4th and 6th positions of the fused thiophene ring, there is a bromine atom each connected, and the bromine atom has high electronegativity, which will affect the electron cloud distribution and reactivity of the compound. The ester form of the carboxyl group is connected at the 2 position, that is, -COO - is connected to the previous 2-ethylhexyl group to form an ester bond. The existence of this ester bond not only changes the properties of the original carboxylic acid, but also makes the whole molecule have the characteristics of an ester, such as solubility and chemical stability in different solvents.
