| Outline of Final Research Achievements |
The objective of this research was to control the interface between organic thin films and inorganic substrates by covalently tethering the interface through self-assembled monolayers (SAMs) having reactive terminal units. This was achieved by growing polymer brush structures by vapor-depositing monomers on the inorganic surfaces modified with SAMs having either benzophenone, azo, or thiol terminal units. It was revealed that the covalent tethering at the interface has remarkable effects in improving adhesion strength and morphology of the organic layers. The covalent tethering was also effective in improving charge injection from the inorganic electrode to the organic layer. This result was applied for improving the luminescence efficiency of organic light-emitting diodes.
