Description
Summary:A Brønsted acid catalyzed cascade benzannulation strategy for the one-pot synthesis of densely populated poly-aryl benzo[ a ]carbazole architectures is disclosed from easily affordable fundamental commodities. The efficacy of this technique was further validated via the concise synthesis of structurally unique carbazole based poly-aromatic hydrocarbons. Furthermore, the photo-physical properties of the synthesized compounds are thoroughly investigated. Brønsted acid catalyzed cascade benzannulation strategy for the concise synthesis of benzo[ a ]carbazoles is reported. Efficacy of the methodology was further validated by synthesizing structurally diverse, extensive π-conjugated carbazole based PAHs.
