Design of solution processable small molecules for efficient electron transport in organic optoelectronic devices |
| 초록 |
Simple, inexpensive, low-temperature and solution processable fabrication methods are considered attractive in organic optoelectronic devices such as organic solar cells (OSCs) and organic light-emitting diodes (OLEDs). Previous our study investigated new synthesized electron transporting materials (4-(2,3-diphenylquinoxaline-5-yl)phenyl)diphenylphosphine oxide (QxTPPO1) consisting of quinoxaline and phosphine oxide moieties, which provide solution processing and tuning the work function of metal cathodes via dipole moment, leading to efficient electron transport. For more effective electron transport, well-matched energy levels between the active later and electron transport layer (ETL) are required due to the different energy levels of the active layers in OSCs and OLEDs. Herein, we design the new electron transporting materials via control of additional functional groups to quinoxaline in QxTPPO1 for efficient electron transport in OLEDs and OSCs, respectively. |
