Allgemeine Beschreibung
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.
Anwendung
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.
