Functional Block-co-polymeric Ligands for Quantum Dot Electroluminescent Devices |
| 초록 |
Quantum Dots (QDs) have been studied for some time as a source of electroluminescence for next generation display device. They have various advantages such as excellent light stability, clarity, lifetime, and low cost. However, defects on the surface of QDs lead to a decrease in photoluminescence quantum yield. Ligand exchange can be used to reduce surface defects of QDs and to increase the efficiency and lifetime of QD photoluminescence. Here, we have designed and synthesized the block copolymer ligands. The ligands constituted N-vinylcarbazole (NVK) as the functional group for hole transfer, and a bitholane terminated acrylate derivate (BTM) as an anchoring group to QDs’ surface. The 1H nuclear magnetic resonance (1H NMR) was utilized to understand the structure of molecules. Further we have confirmed the optical properties of both polymer and polymer-QD hybrids. |
