A powerful method : A variety of sterically crowded, substituted carbazoles have been prepared from anilines and biphenyl compounds (see scheme). The method enabled the preparation of 2,2′‐dicarbazolyl‐1,1′‐biaryl compounds, which show excimer (or exciplex) emissions with significant solvent dependency.
