Charged phenanthroimidazole derivatives for small organic molecular based Light-Emitting Electrochemical cells |
| 초록 |
Electroluminescent properties of host - dopant LEC devices based on small molecular ions have been investigated. In spite of the low luminescence from emitter, most of the EL originated from the emitting species. The device studied in this paper yield a maximum brightness of 4225 cdm-2 at a current efficiency of 0.43 cdA-1. Over a 5-fold increase in the maximum brightness and around a 2˗fold increase in the current efficiency at peak brightness was exhibited by the present LEC device compared to a host-only device (ihpypn-LEC). This study emphasize the importance of phenanthroimidazole derivative (ihpypn) as host material in LEC devices. Further modification of host material may be aimed towards suppressing high luminescence from the host molecules. |
