Usage

General Description

Tetrabromo-thieno[3,2-b]thiophene is a chemical compound consisting of a thieno[3,2-b]thiophene backbone, a heterocyclic compound, which has been substituted with four bromine atoms. The bromine atoms contribute to the compound's heavy and highly polar nature. TETRABROMO-THIENO[3,2-B]THIOPHENE can participate in a range of chemical reactions due to the reactivity of the bromine atoms and the thiophene rings. It is typically used for research purposes in labs, particularly in the field of organic synthesis and materials science. However, detailed information dealing with its properties and safety profiles is scarce due to its specific nature and less frequent use.

Novel Electron Acceptors Bearing a Heteroquinonoid System. II. Synthesis and Conductive Complexes of 2,5-Bis(dicyanomethylene)-2,5-dihydrothienothiophene, 2,6-Bis(dicyanomethylene)-2,6-dihydrothienothiophene, and Their Derivatives

Novel heteroquinoid compounds as potential electron acceptors, 2,5-bis(dicyanomethylene)-2,5-dihydrothienothiophene (4a), 3,6-dibromo derivative, 2,6-bis(dicyanomethylene)-2,6-dihydrothienothiophene, 3,5-dibromo derivative, and 4,4-dioxide were synthesized by the action of tetracyanoethylene oxide or by a Pd(0)-catalyzed substitution reaction with sodium dicyanomethanide on the corresponding α,α'-dihalo-substituted fused thiophenes.They show effectively diminished on-site Coulomb repulsion owing to the extensive conjugation, and most of their molecular complexes with various electron donors exhibit very high electrical conductivies up to metallic region.In addition, X-ray crystallographic analysis of the complex of 4a with bis(ethylenedithio)tetrathiafulvalene has elucidated that sulfur atoms embedded in 4a molecule are capable of inducing a significant intermolecular interaction, forming a sheet-like network structure.
