New Photo Crosslinkable Polymer as Hole Transport Material Applied to Solution - Processed Multi-Layered Organic Light Emitting Diodes |
| 초록 |
Lately, vacuum processed organic light emitting diodes (OLEDs) have been commercialized because of their easy fabrication to multi-layers but they spend a long time and lots of costs to implement OLED device. To overcome these disadvantages, solution-processed OLEDs can be a fine alternative. However, they have a disadvantage that it is difficult to fabricate the multi-layered device because they tend to dissolve the under layer solution by the upper layer’s. So, to resolve this problem, using the photo-crosslinkable system can OLED device be performed more easily. In this work, a new hole transport material, PX2Cz is synthesized by introducing photo crosslinkable group, (Chloromethyl)-3-methyloxetane. It is readily crosslinked by irradiating the UV light under the optimized condition. Especially, the performance of OLED device with PX2Cz shows the result that external quantum efficiency is higher than that of PVK based OLED device and also has low turn-on voltage. |
