We are accelerating the development of materials for the solution-process OLEDs. High-performance small molecules for EML and platform polymers with reduced the molecular weight for HIL/HTL have been developed as the best practice for highresolution printed OLED panels. Further, no-diffusible pdopants have been successfully developed that are key materials for improving the performances of OLEDs produced by solution processes.

High‐performance, ink‐jet printable OLED materials have been successfully developed. Our wide libraries of platforms and small molecule hosts were effective for improving efficiency and lifetime of OLEDs. For wide color gamut, new emitters with deep in color and narrow full‐width at half maximum were developed. Further, solvent systems having physical properties suitable for improving film uniformity in pixels were found.
