2,2'-BITHIOPHENE Chemical Properties,Usage,Production

Description

2,2'-bithiophene is an intermediate widely used for the synthesis of small molecules or polymer semiconductors in application of organic electronics.?It has proven that?2,2'-bithiophene exists as a mixture of the cis-like and the trans-like planar structures. 5,5'-positions of?2,2'-bithiophene are easily accessible for bromination and stannylation to give 5,5'-dibromo-2,2'-bithiophene or 5,5'-trimethylstannyl-2,2'-bithiophene, which can be used for direct arylation reactions.

Chemical Properties

white to light yellow crystal powder

Uses

2,2’Bithiophene is a reactant in the preparation of thienophenyl compounds.

Uses

2,2'-Bithiophene is used as a precursor in the preparation of 5,5'-bis(trimethylstannyl)-2,2'-bithiophene , which is used for the synthesis of small molecules and polymer semiconductors for organic field-effect transistor (OFETs), organic light-emitting diode (OLED), Plastic Light Emitting Diode (PLED) and Organic Photovoltaic (OPV) applications. It is associated with aryl iodides and involved in rhodium catalyzed arylation of heteroarenes.

Uses

2,2′-Bithiophene can be polymerized to form poly(2,2′-Bithiophene) which can be electrodeposited on indium tin oxide (ITO) substrates for the fabrication of electrochromic devices. It can also be used in the formation of electrode material for the development of supercapacitors.

Definition

ChEBI: A thiophene derivative that consists of two thiophene rings connected by a 2,2'-linkage.

Synthetic Communications, 19, p. 307, 1989 DOI: 10.1080/00397918908050983

General Description

2,2′-Bithiophene is an electron transporting material with the π-electrons present in the system that facilitate charge mobility.
