General description

Lauryl terminated poly(3,4-ethylenedioxythiophene), bis-poly(ethyleneglycol) (PEDOT:PEG) is a conductive polymer that can be used as a hole injection layer (HIL) in organic electronics. It has a conductivity of 0.4 Scm-1 and a work function of 4.33eV. It forms a non-acidic solution which contains the perchlorate doped PEDOT-co-PEG.


PEDOT:PEG can be used as a hole transporting layer (HTL) that can be coated on indium tin oxide (ITO) substrate for the fabrication of polymeric solar cells (PSCs). It can also be used in the development of other electronic devices which include organic light emitting diodes (OLEDs) and organic thin film transistors (OTFTs).

Features and Benefits

The block copolymer structure renders the conducting polymer PEDOT highly dispersible in organic solvents. Nitromethane has a suitable volatility for spin coating.
