Photoprocessed and micropatterned conjugated polymer LEDs

Advanced syntheses and microfabrications of conjugated polymers, C60-containing polymers and carbon nanotubes for optoelectronic applications

“…16(b) represent nonfluorescent components associated with the cisisomer. While the conducting patterns thus prepared may find applications in certain electronic and photonic devices, the photolithographic method has also been applied successfully to micropattern electroluminescent conjugated polymers [558] including PPV [559].…”

OLED Displays on Plastic

“…Conventional photolithography techniques are severely limited due to the sensitivity of the organic layer to moisture, oxygen, and solvents (Lidzey et al 1996). However, a photolithography technique using conventional photoresist and metal dry etching has been developed (Pschenitzka et al 2001).…”

Patterning π-Conjugated Polymers

“…[29] In related work, the photolithography of PPVs has been studied with the aim of fabricating patterned LEDs. [30] The procedure involved depositing, photoimaging, and developing a positive photoresist on top of a poly(2,5-dialkoxy-p-phenylenevinylene) emissive layer, depositing metal onto exposed PPV and removal of the remaining resist. The procedure was found to lower the luminescent yield of the polymer by 35 %.…”
