Description

3,4-Ethylenedioxythiophene (EDOT) is a highly versatile heterocyclic organic compound with the molecular formula C₆H₆O₂S. Its IUPAC name, 2,3-dihydrothieno[3,4-b][1,4]dioxine, reflects its fused-ring structure combining thiophene and dioxane moieties. This monomer is a critical precursor in the synthesis of conductive polymers, particularly poly(3,4-ethylenedioxythiophene) (PEDOT), renowned for its exceptional electrical conductivity, optical transparency, and environmental stability. EDOT is supplied as a high-purity reagent (>98%) suitable for electrochemical polymerization, organic electronics, and advanced material research. Its compatibility with aqueous and organic solvents makes it ideal for thin-film deposition, flexible electronics, and antistatic coatings. Store under inert conditions to prevent premature polymerization.

Application

3,4-Ethylenedioxythiophene (EDOT) is primarily used to synthesize PEDOT, a conductive polymer applied in organic light-emitting diodes (OLEDs), solar cells, and biosensors. Its derivatives serve as key components in transparent conductive films for touchscreens and smart windows. EDOT-based polymers also exhibit excellent biocompatibility, enabling use in neural interfaces and medical device coatings.
