A Facile Synthesis of Blue Luminescent [7]Helicenocarbazoles Based on Gold‐Catalyzed Rearrangement‐Iodonium Migration and Suzuki–Miyaura Benzannulation Reactions

Abstract

New azahelicenes having interesting photophysical properties have been prepared in a four-step sequence. These [7]helicenocarbazoles are efficient blue luminophores, demonstrating the utility of gold catalysis in the preparation of advanced materials.
