Patterning of conjugated polyfluorenes containing photo-crosslinkable oxetane units for PLEDs and OTFTs applications. |
| 초록 |
We have synthesized a photo patternable blue light-emitting polyfluorene (PF) derivative containing cross-linkable oxetane units. Poly(9,9-bis-(4-octyloxy-phenyl)-fluorene-2,7-diyl-alt-9,9-bis-((3-hexyloxy-3’-ethyl)-oxetane)-fluorene-2,7-diyl) has been synthesized by Suzuki coupling polymerization. The relationship between patterning property and several variables such as the intensity of the exposed UV light, the concentrations of additives, has been studied by using optical microscope UV/visible spectroscopy, photoluminescence and scanning electron microscope (SEM). We obtained fine patterns with 10 μm resolution using the polymer film after exposure and development. This patterning method using conjugated polymers can be applicable to make fine pixels for PLEDs and OFETs. |
