Abstract
AbstractIn this article, we demonstrate an atom economical, practical, mild and selective HBF4‐catalyzed 1,6‐conjugate addition of carbazoles topara‐Quinone Methides (p‐QMs) to access 3,6‐bis‐diarylmethyl‐ and mono‐diarylmethyl carbazoles. This metal and additive free protocol provides convenient access to the substituted carbazole derivatives in moderate to excellent yields with a good functional group tolerance. It was found that a couple of 3,6‐disubstituted carbazoles showed interesting photophysical properties and, therefore, might potentially find some applications as host materials in OLEDs.
