Description

General description

PDPP2T-TT-OD is thiophene based conducting polymer with diketopyrrolo-pyrrole (DPP) as the electron deficient group and octyldodecyl acting as a pendant attachment. Its structure has a DPP-thiophene and a variable bithiophene (2T). It has a high charge carrying mobility that makes it useful in the development of organic electronics based devices.

Application

PDPP2T-TT-OD can be used as a π-conjugating polymer that can be used in the fabrication of a variety of devices such as organic thin film transistors (OTFTs), photovoltaic cells, polymeric solar cells and field effect transistors (FETs).

Xerox demonstrated device performance on a n-doped silicon wafer with 100 - 300 nm native SiO2 dielectric modified with an octadecyltrichlorosilane self-assembled
monolayer. An XSC4p film was deposited by spin-coating a 0.5 – 0.7 wt. % polymer solution at 1000 rpm for 60 sec. The film was dried in a vacuum oven for 10 min at 80
°C and then thermally annealed at 140 °C for 10 min. Gold source-drain electrodes were deposited by vacuum evaporation using a shadow mask (90 micrometer channels).
The electrical performance was characterized using a Keithley SCS-4200 system. The reported mobility is the average saturated mobility of four devicεs ± the standard
deviation.
