- One-pot two-step synthesis of: N -arylcarbazole-based skeleton
-
A highly site-selective, one-pot, sequential C-N and C-C bond forming process was developed, affording a carbazole-based skeleton that contains biphenyl and diarylacetylene cores. The success of this process is attributed to the use of fluorinated iodoarenes as the starting material, the fluorine group of which preferentially reacts with carbazole. The subsequent coupling of the intermediate iodinated N-arylcarbazole with arylboronic acid or arylacetylene produced the desired products. The intermediate underwent a Pd-catalyzed Ullmann coupling with excess fluorinated iodoarenes in the absence of arylboronic acid or arylacetylene, resulting in Ullmann coupling products in a one-pot process.

- Blue fluorescence from the ligand and yellow phosphorescence from the iridium complex: High-efficiency wet-processed white organic light-emitting device
-
We synthesized four carbazole modified blue-emitting fluorescent ligands. These ligands coordinated with Ir3+ and four yellow-emitting phosphorescent complexes were obtained. A high-efficiency (current efficiency 20.6 cd/A) yellow electrophosphorescence device was wet-fabricated using the complex as a guest. The ligands can harvest and transfer energy to the complexes and a high efficiency (~18 cd/A) white-light emitting device (CIE 0.31, 0.39) was obtained using the ligand as the blue-fluorescence emitter and the complex as the yellow-phosphorescence emitter. Therefore, the ligand can be a coordinator, an emitter and partly, a host. This is beneficial to device efficiency and saving cost for large-scale manufacturing.
