9-(1-naphthalenyl)-10-(4-(2-naphthalenyl)phenyl)anthracene

Uses

9-(1-Naphthalenyl)-10-(4-(2-naphthalenyl)phenyl)anthracene (BH) could be used as a blue host in the fabrication of blue OLED device. BH is a host material with a high molecular weight and a gre at steric hindrance by introducing bulky aromatic rings and rigid cardo structure, and BH have a high thermal stability (Tg of 131 °C; Tm of 274 °C; and Td of 367 °C).
With a ET of 1.50 eV, BH is a very popular blue fluorescent host material due to its large band gap (Eg = 3.0 eV).
