Aza-dicyclopenta[a,g]naphthalenes: controllable seesaw-like emissive behavior and narrowband AIEgens.

ABSTRACT: Molecular motions significantly influence the emissive behavior and properties of organic fluorescent molecules. However, achieving controllable emission remains a major challenge for fluorophores. In the case of aggregation-induced emission luminogens (AIEgens), the desired properties of aggregated emission and narrowband spectrum demand molecular motion patterns that inherently oppose each other. A nitrogen-containing dicyclopenta[a,g]naphthalene scaffold was discovered as a controllable luminogenic structure through a highly efficient one-step intermolecular cascade reaction. By carefully balancing molecular motions and introducing additional nitrogen atoms into the skeleton, pyrrole-conjugated dicyclopenta[a,g]naphthalenes with aggregation-caused quenching (
