| 英文摘要 | Two novel star-shaped oligotriarylamines with planar triphenylamine core and peripheral triarylamine groups, namely FATPA-T and FATPA-Cz, were synthesized by Suzuki cross-coupling reaction. The molecular design imparts the materials with the following features: (i) excellent thermal stabilities with quite high glass transition temperatures (237 degrees C for FATPA-T and 272 degrees C for FATPA-Cz); (ii) good solution-processability; (iii) good hole mobility, efficient hole injection, and electron-blocking functions. Furthermore, their optoelectronic properties can be modulated by the peripheral triarylamine groups. For example, FATPA-T with triphenylamine peripheries shows the significantly red-shifted absorption and emission, as well as the small band gap as compared to FATPA-Cz with carbazole peripheries. Double-layer Alq(3)-emitting OLEDs using FATPA-T or FATPA-Cz as hole-transport layer by spin-coating method were fabricated, and the FATPA-Cz-based devices show greatly improved performance as compared to standard NPB-based device by vacuum-evaporation of NPB. The optimized three-layer Alq(3)-emitting OLEDs by using FATPA-Cz and NPB as double hole-transport layers exhibit the maximum current efficiency of 6.83 cd/A, which is the highest for the Alq3-based green emission under the similar device structures. The advantages of solution-processablity and very high T-g make the star-shaped oligotriarylamines ideal substitutes for conventional arylamines as hole-inject and hole-transport materials. |
