Description

General description

3,4-Dimethoxythiophene (DMOT) is a monomer and a precursor which can be synthesized by ring closure reaction of 2,3-dimethoxy-1,3-butadiene and sulfur dichloride in hexane medium. It is an oligothiphene that is majorly used in the development of electroactive materials for organic electronics based applications.

Application

Building block in the synthesis of an N₂S₂-N₄ porphyrin dyad used to study photoinduced energy transfer.

DMOT can be trans-esterified to form 3,4-ethylenendioxythiophene (EDOT). It can further be polymerized to produce PEDOT which can be used as a conductive polymer in π-conjugated systems. It can be polymerized to form poly(dimethoxythiphenes) which can potentially be used in the fabrication energy storage devices on electrochemical doping.
