Outline of Final Research Achievements

Completely horizontally oriented fluorescent guest molecules doped into organic thin films were successfully attained by vacuum vapor deposition. Applying the ultimate orientation to organic light-emitting diodes, light-outcoupling efficiency of 39% was achieved; the value was over 50% higher than those of randomly oriented films. Through the project, it was demonstrated that use of long linear-shaped guest molecules is of great importance for realizing horizontal orientation of the guest molecules.
In addition to the guest orientation control in vapor deposited films, the orientation formation process was investigated even in spin-coated films. The investigation found that the solution flow during deposition is the dominant factor to control orientation.
