Abstract
- Abstract: Reported here is the synthesis of pyridine-functionalized porous polymers, which are designed as homogeneous-like base catalysts. These highly porous catalysts have adjustable pyridine contents, high BET surface area (312–649m2/g), large pore volume (0.5–2.0cm3/g) and rapid swelling property, thus they efficiently combined the advantage of both homogeneous and heterogeneous catalysts. The exposure degree of active sites in our homogeneous-like catalysts has been evaluated by Cu2+ adsorption, giving similar capacity with homogeneously dissolved poly-4-vinylpyridine. In the Knoevenagel condensation, these materials exhibit excellent activity and stability compared with Mg–Al hydrotalcite and magnesia as well as homogeneous base catalyst of poly-4-vinylpyridine.
