| 제목 | Light-Emitting Properties of New Polyimides Containing Ethynylene Unit in the Main Chain |
| 초록 | Polymers with extended ∏-conjugated system are drawing a great attention due to their potential application as luminescent materials. We have synthesized the new polyimides containing ethynylene link by conventional two-step polycondensation of dianhydride and counter diamines. In the present work, we studied the electro- and photoluminescent device characteristics of novel polyimides containing ethynylene unit in the main chain. The ethynylene unit is introduced into the polymer main chain to achieve enhanced luminescence performance and electric conductivity. The morphologies of polyimide films were examined by optical microscope. Light-emitting devices of construction ITO/PEDOT/PIs/BAlq3/LiF/Al were fabricated from multi-layer films of the polymer and their electrical performances were measured and discussed with respect to the chemical structure of the polymers.
