中文摘要 | 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. |
