General description

3,4-Ethylenedithiothiophene (EDTT) is a dithiin based conducting polymer that is a sulfur analog of 3,4-ethylendioxythiophene (EDOT) that is majorly used in optoelectronic and electrochemical devices.[1][2]

Application

EDTT can be electrochemically oxidized in acetonitrile to form poly(EDTT) films on the surface of the electrodes, which can be used in the fabrication of organic light emitting diodes (OLEDs) and organic photovoltaics (OPVs).[1][3][4]
