Abstract
Porous aromatic frameworks (PAFs) featured by the high density of phenyl rings in their robust frameworks are attractive platforms for catalysis because of their extremely high stability, high surface area and adjustable pore size. In this paper, two novel PAF‐supported ionic liquids were constructed by introducing ionic liquid units onto the framework of a PAF material named PAF‐111 using a series of stepwise post‐synthetic modifications. The basic PAF‐supported ionic liquid with hydroxyl anion exhibited high catalytic activity, high stability and could undergo at least 10 cycles without any activity loss when catalyzing Knoevenagel condensation reaction under aqueous conditions. It is expected that our study will further promote the development of designing and applying functional PAF materials for catalysis in aqueous system.Keywords
