Microlithographic process for patterning conjugated emissive polymers

The spatially confined synthesis of emissive conjugated polymers—compatible with existing 1C fabrication technology—is described, which can be used to create well‐defined micrometerscale patterned organic LEDs (see cover). The Figure shows the first step in the photolithographic process, which is followed by irradication, to produce a latent image, and development, resulting in patterned polymer. magnified image
