摘要 在水/乙醇混和体系中制备了三苯基膦稳定的金纳米粒子(GNPs)溶液。GNPs的粒径为5 nm,在548 nm有典型的表面等离子吸收。在不使用其它相转移分子的情况下,GNPs可以容易地转移到有机溶剂如二氯甲烷中,并得到可再分散于有机溶剂或水中的固体粉末,为制备可应用于不同的物理化学环境中的表面功能化GNPs提供了优异的初始化合物。 Au nanoparticles stabilized by tripbenylphosphine(TPP) with diameter about 5 nm were synthesized. The nanoparticles could be transferred into dichloromcthane(DCM) from water/ethanol solution without addition of any surfacrant. Such a material could be used to synthesize various surface functionalized Au nanoparticles in organic solvents via ligand exchange.
