Synthesis and Characterization of Indenofluorene-basedWhite Light-Emitting Copolymers |
| 초록 |
An indenofluorene-based copolymer containing blue-, green-, and red light-emitting moieties was synthesized by Suzuki polymerization and examined for application in WPLEDs. The EL characteristics were fine-tuned from the single copolymer through incomplete fluorescence energy transfer by adjusting the composition of the red/green/blue units in the copolymer. The EL device using the indenofluorene-based copolymer containing 0.01 mol% BT and 0.02 mol% DBT units (PIF-BT01-DBT02) showed a maximum brightness of 4,088 cd/m2 at 8 V and a maximum current efficiency of 0.36 cd/A with Commission Internationale de L’Eclairage (CIE) coordinates of (0.34, 0.32). The EL emission of PIF-BT01-DBT02 was stable with respect to changes in voltage. |
