Synthesis and Catalytic Performance of Organic–Inorganic Hybrid Mesoporous Material Having Basic Nanospace

Basic nanospace was synthesized by the homogeneous modification of FSM-16 with 3-(triethoxysilyl)pyridine, which is a rigid substrate without an alkyl chain as linker. Aldol condensation of butanal gave the corresponding dimer in high yields over 3-(triethoxysilyl)pyridine-modified FSM-16. A copper-pyridine complex was immobilized within the interior of FSM-16 using the modified pyridyl group as a ligand and the oxidative coupling polymerization of 2, 5-dimethylphenol proceeded with high regio-selectivity
