Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A novel class of luminescent platinum(II) bzimb (1, 3‐bis(<italic>N</italic>‐alkylbenzimidazol‐2′‐yl)benzene) complexes has been designed and synthesized. With the incorporation of various substituents on the anionic phenyl ring of the bzimb ligand, the emission color can be readily tuned. Their photophysical, electrochemical and electroluminescence properties have been studied. These platinum(II) bzimb complexes have been demonstrated to be capable of serving as phosphorescent dopants. Efficient solution‐processable OLEDs (organic light‐emitting devices), with a maximum external quantum efficiency of up to 4.85 %, can be achieved. This class of platinum(II) bzimb complexes represents a promising class of phosphorescent dopants for solution‐processable OLEDs.</p> </abstract>
