The synthesis of the DPyBP (D = DMAC, PXZ, dDPACz) family of emitters is outlined in Scheme 1. Key intermediate, 12-bromodibenzo[f,h]pyrido [2,3-b]quinoxaline 1 was synthesized in good yield via the condensation of 5-bromopyridine-2,3-diamine with phenanthrene-9,10dione. The target compounds DMACPyBP, PXZPyBP and DPACzPyBP were then obtained in very good yields (over 70%) through palladium-catalyzed Buchwald-Hartwig cross-coupling reactions of 1 with the corresponding donors. The identity and purity of these three target emitters were confirmed using a combination of nuclear magnetic resonance (NMR) spectroscopy, high resolution mass spectrometry (HRMS), elemental analysis, and melting point determination.
