Phosphorescent Pt(ii) acetylacetonate complexes bearing 9-(pyrimidin-2-yl)-9H-carbazole ligand: syntheses, photophysical properties and OLED applications

Complexes Pt(TBPCH)(dpmn) 2a and Pt(TBPCH)(dnmn) 4a were prepared for fabricating OLED devices. The devices using 2a emitted at 525 nm with an EQE max of 4.0% at CIE coordinates of (0.34, 0.51), and the devices using 4a emitted at 585 nm with an EQE max of 15.1% at CIE coordinates of (0.50, 0.48).
