Specifications | MSDS | Literature and Reviews


Tetrabromothiophene (CAS number 3958-03-0) is a fully brominated thiophene. Fully functionalised around the thiophene ring, tetrabromothiophene is used for the construction of further conjugated semiconductors as thiophene, fused thiophene or poly-fused thiophene structures in application of organic electronics, i.e. polymer solar cells and organic field-effect transistors. Fused thieno[3,2-b:4,5-b’]diindoles can be prepared with tetrabromothiophene as the starting material. Tetrabromothiophene is also an intermediate for the preparation of 3,4-dibromothiophene.

Derived from tetrabromothiophene, TPTn and TPTEn, both bearing one tetraphenylthiophene-core and either peripheral alkoxyl chains or 3,4,5-trialkoxybenzoate groups, form square, rectangular or hexagonal columnar phases depending on the mesogenic core structures and the chain length of aliphatic tails. Besides, TPTn and TPTEn luminescent liquid crystal molecules show obvious aggregation-induced emission (AIE) characteristics, the fluorescence emission intensity values measured in the aggregated state were hundred times higher than those values measured in benign solvents [1].
