CAS 124638-53-5: Tetrabromo-thieno[3,2-b]thiophene

2,3,5,6-Tetrabromo-thieno[3,2-b]thiophene

2,3,5,6-Tetrabromo-thieno[3,2-b]thiophene is a processable brominated polymeric material that can be used in transistors and other electronic devices. It has been shown to be suitable for use in the fabrication of organic field effect transistors (OFETs) with good performance characteristics. 2,3,5,6-Tetrabromo-thieno[3,2-b]thiophene has been successfully synthesized by a variety of routes including the addition of bromine to thiophene followed by quaternization with dialkyl halides or diketones. This compound has also been used as an ingredient in copolymers such as poly(thiophene-2,5-diyl)-co-(poly(ethylene glycol)) and poly(ethynyl methacrylate).
