- •
Using a dual-core chromophore, two new emitters of blue light were synthesized.
- •
Side groups of DCP-AP and DSF-AP prevent excimer formation and improve efficiency.
- •
Compared with AP core lacking side groups, new emitters showed higher efficiency.
- •
The power efficiency increased by 32% for DCP-AP compared to the AP core.
- •
The luminance efficiency of DCP-AP was observed to be 31% greater than the AP core.
