N-Donor/Fluorenyl o-Carborane Fluorophores with Strong Crystallization-Induced Emission

Wang, Zhaojin; Wang, Tianyu; Zhang, Chi; Humphrey, Mark


N‐Donor/fluorenyl (D/Fl) substituted o‐carborane triads (2 a–2 e) exhibit strong crystallization‐induced emission. Crystallographic studies reveal H⋅⋅⋅π interactions in 2 a–2 e and π⋅⋅⋅π interactions in 2 c/2 d/2 e contributing to the close packing to varying degrees. In solution, the D‐Cb‐Fl triads exhibit strong quenching of charge‐transfer (CT) emission with quantum efficiencies (Φ) less than 0.05, whereas in solvated aggregates, they display blue‐shifted CT emission and enhanced Φ values...[Show more]
