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.[1][2][3]

Application

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).[4] 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).[5]

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.
