Applicazioni

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.

Note

Incompatible with strong oxidizing agents. Keep container tightly closed in a dry and well-ventilated place.
