A SiO2-supported molecularly imprinted Pd complex with SiO2-matrix overlayers was prepared as a Suzuki cross-coupling catalyst. A ligand on the supported Pd complex was used as a molecular imprinting template to create the reaction space. The structures of the supported and molecularly imprinted Pd complexes on SiO2 were determined by solid-state MAS 13C, 29Si, and 31P NMR; diffuse reflectance UV/vis;
