Synthesis and study of functionalized metal nanoparticles and organic perfluoroalkylated chromophores

Unrestricted Functionalized palladium nanoparticles were produced when Pd(II) was reduced in the presence of a variety of molecular capping agents. Silver nanoparticles passivated with a variety of organic species were easily prepared through exhaustive ligand exchange with myristate-capped precursor particles. These precursor nanoparticles may be conveniently prepared in bulk amounts, giving access to a large variety of functionalized nanoparticles that may be difficult to prepare via existing methods.; We have synthesized a number of fluorescent compounds that are derivatized with perfluoroalkyl groups. Both free radical and copper-mediated processes have been employed, as well as a novel and facile technique that introduces a perfluoroalkyl ether at the 9-position of fluorenes. None of these perfluoroalkylated chromophores have been previously reported in the literature.

无约束功能化钯纳米颗粒可通过在多种分子封端剂存在下还原二价钯（Pd(II)）制得。通过与肉豆蔻酸酯封端的前驱体纳米颗粒进行彻底配体交换，可便捷制备得到经多种有机组分钝化的银纳米颗粒。此类前驱体纳米颗粒可便捷地批量合成，由此可获得大量通过现有方法难以制备的功能化纳米颗粒；本团队合成了多种经全氟烷基衍生化的荧光化合物，研究中采用了自由基反应与铜介导合成两条路径，同时开发了一种可在芴的9位引入全氟烷基醚的新颖简便方法。此类全氟烷基化发色团此前未见文献报道。
