Synthesis and photoelectric properties of a solution-processable yellow-emitting iridium(iii) complex

A heteroleptic iridium(iii) complex [(CzhBTZ)₂Ir(fpptz)] was synthesized for efficient and stable PhOLEDs by spin-coating. It shows a maximum brightness of 9617 cd m⁻², a maximum current efficiency of about 9.43 cd A⁻¹, and International Commission on Illumination (CIE) coordinates of (0.42, 0.56).
