New blue-violet emitters based on an indenopyrazine core for OLEDs |
| 초록 |
A promising class of blue–violet emitters based on a new functional core, the indenopyrazine group, has successfully been synthesized for the first time by substitution with bulky m-terphenyl side groups in the ortho, meta, or para positions. When the synthesized compounds were used as emitting layers in non-doped OLED devices, a related trend was observed in their optical properties. In particular, the OLED containing the para-substituted derivative was found to exhibit excellent characteristics, with maximum EL emission at 423 nm, a full width at half maximum of 42 nm, pure violet emission with CIE coordinates (0.173, 0.063), and an external quantum efficiency of 1.88 %. |
