Supramolecular networks

A networked supramolecular POM-based hybrid catalyst has been synthesized by Ikegami and coworkers via the self-assembly of [PWi2O40]3 and non-crosslinked copolymer based on N-isopropylacrylamide (NIPAM) and ammonium cations (Figure 6.7) [124, 125]. This heterogeneous NIPAM-POM hybrid catalyst showed very high catalytic activity for the epoxidation of allylic alcohols with H202 (e.g., up to 35 000 TON for phytol). In addition, the oxygenation of amines and sulfide could be... 

The non-cross-linked poly(acrylamide) 79 bearing the triarylphosphino groups was prepared from the acrylamide monomer and diphenyl(styryl) phosphine. The metal-directed self-assembly process between the non-cross-linked polymer ligand 79 and the palladium species afforded the networked supramolecular complex 80 [106, 109]. The complex catalyzed the Suzuki-Miyaura coupling [106,109] and the same concept, a tungsten-based self-assembly complex, has also been developed for the catalytic oxidation process.
