The Influence of PPV derivative by substituted tetrakis-ethylhexyloxy groups for PLEDs |
| 초록 |
New electroluminescent polymer with tetrakis-alkoxy group, poly[2,3,5,6-tetrakis(2-ethylhexyloxy)-1,4-phenylenevinylene] (TEH-PPV), has been synthesized by the Gilch polymerization. TEH-PPV with tetrakis-ethylhexyloxy groups in phenylene unit can get shorter conjugation length than MEH-PPV, and had more blue shifted absorption and emission peaks due to steric hindrance. Tetrakis-ethylhexyloxy groups induced very conjugated backbone is twisted. And, they can enhance the internal efficiency of the conjugated polymer as emissive layer in PLED because of the restraint of inter-chain interaction by the avoidance of close packing to give decent device performance. |
