Eight bicarbazole (BCz) compounds, 9,9′‐diphenyl‐3,3′‐bicarbazole (PhBCz), 9,9′‐di(2‐pyridyl)‐3,3′‐bicarbazole ( o ‐PyBCz), 9,9′‐di(3‐pyridyl)‐3,3′‐ bicarbazole ( m ‐PyBCz), 9,9′‐di(4‐pyridyl)‐3,3′‐bicarbazole ( p ‐PyBCz), 9,9′‐di(5‐pyrimidinyl)‐3,3′‐bicarbazole (PmBCz), 9,9′‐di(2‐pyrazinyl)‐3,3′‐bicarbazole (PzBCz), 9,9′‐di(4‐isoquinolinyl)‐3,3′‐bicarbazole (4‐IqBCz), and 9,9′‐di(5‐isoquinolinyl)‐3,3′‐bicarbazole (5‐IqBCz), that can be divided into three categories: category one with ortho , meta , or para pyridyl substituted BCz (PhBCz as a reference), category two with pyrimidinyl or pyrazinyl substituted BCz, and category three with 4‐ or 5‐isoquinolinyl substituted BCz, were synthesized and characterized in terms of photophysical, thermal, and electrochemical properties. Moreover, these compounds were utilized to codepositing with copper iodide to form luminescent copper iodide complex doped films in situ, whose emission colors range from green to yellow and might be employed as the emissive layer in organic light‐emitting diodes (OLEDs).
