Naphthyl substituted triphenylamine and its derivatives with bromine atoms were synthesized and investigated. The respective glass transition temperatures of the materials were estimated to be in a range 65–137 °C, which can provide morphologically-stable amorphous films for applications in organic light emitting diodes. The compounds possess adequate ionization potentials (5.5–5.75 eV), high hole drift mobilities (>10⁻³ cm²/V·s) and suitable triplet energies (∼2.4 eV), which make them suitable hole transporting materials for use in red phosphorescent organic light-emitting diodes. A superior peak efficiency of 17.9% (31.4 cd/A and 26.9 lm/W) was achieved in a device having hole transporting layer of tris[4-(1-naphthyl)phenyl]amine. Furthermore, the device gave efficiencies of 17.7% and 16.6% recorded at luminance levels of 10² and 10³ cd/m². The efficiency drop from the maximum to the value recorded at the luminance of 10³ cd/m² for the device was only 7%.

合成并研究了萘基取代的三苯胺及其具有溴原子的衍生物。估计材料的各自玻璃化转变温度在65–137°C的范围内，可以为有机发光二极管提供形态稳定的非晶膜。这些化合物具有足够的电离势（5.5–5.75 eV），高空穴迁移率（> 10 ^-3 cm ²/ V·s）和合适的三重态能量（〜2.4 eV），这使其成为适用于红色磷光有机发光二极管的空穴传输材料。在具有三[4-（1-萘基）苯基]胺的空穴传输层的器件中，获得了17.9％（31.4 cd / A和26.9 lm / W）的出色峰值效率。此外，该装置在10 ²和10 ³  cd / m ^2的亮度水平下记录的效率为17.7％和16.6％。该器件的效率从最大值下降到以10 ³  cd / m ²的亮度记录的值仅为7％。
