Perfluoroarene-arene interaction cocrystal of perfluorocarbazoles toward IEF-enhanced photocatalysis.

ABSTRACT: The photocatalytic generation of highly reactive oxygen species (ROS) such as H₂O₂ and ˙OH, using molecular oxygen without sacrificial reagents or metal catalysts, is a significant challenge. To address this, we introduce a novel approach by adding a second perfluoroarene layer to arene-perfluoroarene cocrystals, which enhances the dipoles between the π-hole and π-donor layers, thereby increasing the internal electric field (IEF) and improving charge separation. We successfully synthesized a series of perfluorocarbazole derivatives through a Pd-catalyzed C-Br/C-F amination reaction. Three cocrystals, Pe-FPC (1 : 2), Pe-FMC (1 : 2), and TP-FPC (1 : 1) were synthesized, with Pe-FPC (1 : 2) exhibiting exceptional photocatalytic activity. Pe-FPC (1 : 2) effectively degrad
