Abstract

A white OLED with a maximum EQE of 20.1%, CIE coordinates of (0.33, 0.33) and CRI of 80 is fabricated based on platinum(II) bis(N-methyl-imidazolyl)benzene chloride (Pt–16). The device emission spectrum and the chemical structure of Pt–16 are shown in the inset of the efficiency versus luminance graph.
