To construct micron-scale materials patterns on organic charge-transport layers is important but challenging for the production of high resolution organic light-emitting diodes (OLEDs). One of the promising candidates to overcome this huddle is Orthogonal Photolithography enabled with fluorous solvents and highly fluorinated photoresist (PR) materials. From the context of this concept, we synthesized a perfluoroether-type calixarene PR and a photoacid generator (PAG) which show a significantly improved solubility in fluorous solvents for PR deposition, pattern develop and stripping. In this poster presentation, we are going to show the synthesis of highly fluorinated photoresist materials, examination their dissolution characteristics, patterning performance, and finally applications to the fabrication of patterned OLED pixels built on an organic hole-transport layer. |
