5,7-Dibromo-2,3-dihydrothieno[3,4-b][1,4]dioxine Chemical Properties,Usage,Production

Chemical Properties

Needle-like solid

Uses

5,7-Dibromo-2,3-dihydrothieno[3,4-b]-1,4-dioxine is used in the preparation of 3,4-ethylenedioxythiophene oligomers with optical and redox properties.

Uses

Used as a monomer in the synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) polymer which are used in electrochromic devices.

General Description

2,5-Dibromo-3,4-ethylenedioxythiophene (DBEDOT) is a monomer which is used in the synthesis of highly conducting poly(3,4-ethylenedioxythiophene) (PEDOT) polymer. This polymer is formed by solid-state polymerisation of DBEDOT and is used widely in organic-light emitting diodes and polymer field effect transistors. DBEDOT is a well-ordered crystalline monomer and produces PEDOT polymer which has a high degree of order.
