研究目的
Investigating the relationship between the single crystal structure of materials and the electroluminescence (EL) performance of doped OLED devices.
研究成果
The study concludes that highly twisted molecular structures, as observed in the single crystal structures of 1,6 DAP-TP and DAC-TP, can improve the EL efficiency of materials by inhibiting rotational and vibrational motions. The doped OLED devices using 1,6 DAP-TP showed higher efficiency than those using DAC-TP, and both compounds satisfied the high-density television display requirements with ultra-deep blue emission.
研究不足
The study is limited to the comparison of two specific compounds and their performance in doped OLED devices. The relationship between single crystal structure and EL performance may not be generalizable to all materials.
