This Account reports the synthesis and characterization of dendrimer-encapsulated metal nanoparticles and their applications to catalysis. These materials are prepared by sequestering metal ions within dendrimers followed by chemical reduction to yield the corresponding zerovalent metal nanoparticle. The size of such particles depends on the number of metal ions initially loaded into the dendrimer. Intradendrimer hydrogenation and carbon-carbon coupling reactions in water, organic solvents, biphasic fluorous/organic solvents, and supercritical CO2 are also described.
本综述报道了树枝状聚合物包裹的金属纳米粒子的合成、表征及其在催化中的应用。这些材料通过将金属离子隔离在树枝状聚合物中，然后进行化学还原以生成相应的零价金属纳米粒子来制备。此类粒子的尺寸取决于最初负载到树枝状聚合物中的金属离子数量。还描述了在水、有机溶剂、双相氟代/有机溶剂和超临界二氧化碳中的树枝状聚合物内氢化反应和碳-碳偶联反应。
