Abstract

  In this paper, a micro-patterned 2-color OLED was fabricated through a sequential solution process based on standard photolithography. Previously, we

developed a sol-gel process to obtain the orthogonality of organic semiconductor against the solvents and chemicals so that we could apply the standard photo-lithography and dry-etch process to achieve micron-size patterns of light-emitting polymers with MEH-PPV and F8T2-based orthogonal polymer semiconductor gel (OPSG) through sequential solution processes.
