Abstract
A novel molecular scaffold, dibenzo[f,h]furo[2,3-b]quinoxaline (3,6-bis(4-isopropylphenyls)-11-phenyldibenzo[f,h]furo[2,3-b]quinoxaline (dP-diBFQ) and furo[2′,3′:5,6]pyrazino[2,3-f][1,10]phenanthroline, were designed, for pure and deep blue emission. OLEDs based on dP-diBFQ shows pure blue emission with CIE coordinates of (0.154, 0.102) and an EQE of 2.28%.
