Porous Aromatic Framework Nanosheets Anchored with Lewis Pairs for Efficient and Recyclable Heterogeneous Catalysis

Lewis pairs (LPs) with outstanding performance for nonmetal‐mediated catalysis reactions have high fundamental interest and remarkable application prospects. However, their solubility characteristics lead to instability and deactivation upon recycling. Here, the layered porous aromatic framework (PAF‐6), featuring two kinds of Lewis base sites (N Piperazine and N Triazine ), is exfoliated into few‐layer nanosheets to form the LP entity with the...
