3,4-DIAMINOTHIOPHENE DIHYDROCHLORIDE Chemical Properties,Uses,Production

Chemical Properties

grey or brown crystalline powder

Uses

3,4-Diaminothiophene dihydrochloride can be used in the synthesis of thieno[3,4-b]pyrazine for thermoelectric applications. It can also be used in the synthesis of acenaphtho[1,2-b]thieno[3,4-e]pyrazine based acceptor molecules for the fabrication of organic transistors.

General Description

This material is a synthetic intermediate for organic electronics materials such as Arylenediimide-thiophene Derivatives for Organic n-channel field-effect transistors. 1
They are also integral to the synthesis of thienopyrazine-based materials as low band gap materials for Organic Photovoltaic applications2 and as copolymer units for sensor applications.3
