| Research Abstract |
It was found that coal-pitch, a mixture of coal tar, could be utilized as an emissive layer for organic light emitting diode. On the PEDOT/PSS-coated ITO electrode, a solution of coal-pitch was spin-coated, and LiF/Al electrode was deposited onto it. The obtained OLED properties depended on the used solvent and it could also be controlled by PTLC method, which is a conventional method for separation in organic chemistry.
