Rational Molecular design of High Mobility Hole Transport Polymers Applicable to Quantum Dot-Light Emitting Diodes |
| 초록 |
Since the researchers found that materials exhibit different optical properties in nano-scale, there were numerous efforts to adopt quantum dot(QD) in various area. In display technology, it is obvious that applying QDs as emitting layer can increase the lifetime and color purity. The problem for commercialization is that QD-based light emitting diode(QD-LED) has not reach proper performance compared with organic-LED. Because the poor performance of QD-LED is derived from its low charge balance due to hole transport material(HTM) with low mobility, new charge transporting materials should be considered as key solution for advanced performance. In this study, we synthesized a polystyrene based new HTM (e.g. P-CzAc), with high mobility and investigated its properties. P-CzAc exhibited much higher hole transport ability (hole mobility=6.21 x 10-7 cm2V-1S-1) compared with poly(9-vinylcarbazole) (PVK). Eventually, P-CzAc based QD-LED performed with low turn-on voltage and high efficiency. |
