- Abstract:
- The fabrication of a poly(3,4-ethylenedioxythiophene) (PEDOT)
pattern is demonstrated. As template, an n-octadecyltrichlorosilane
(OTS) monolayer self-assembled on indium tin oxide (ITO) was
structured by UV–ozone photolithography, resulting in an ITO–
OTS patterned surface. The conducting properties of the ITO were
utilized for the selective electropolymerization of 3,4-ethylenedioxythiophene
(EDOT), whereby the electropolymerization was
inhibited by the insulating OTS. Differently sized PEDOT–OTS
patterns were obtained. The electronic properties of the patterns
were finally evaluated in a test OLED device.
