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.
Application
Used as a monomer in the synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) polymer which are used in electrochromic devices.
Features and Benefits
Polymerisation of DBEDOT can take place under very gentle conditions in the absence of external agents or catalysts.

Prolonged storage ( approximately 2 years) or gentle heating (50-80 degrees C) of crystalline 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT) affords a highly conducting, bromine-doped poly(3,4-ethylenedioxythiophene) (PEDOT), as confirmed by solid-state NMR, FTIR, CV, and vis-NIR spectroscopies. The novel solid-state polymerization (SSP) does not

Many types of batteries have been proposed as next-generation energy-storage systems. One candidate is a rocking-chair-type "molecular ion battery" in which a molecular ion, instead of Li+ , works as a charge carrier. Previously, we reported a viologen-type derivative as
