新的双位硫醇-膦化合物HS(CH(2))(11)OOCC(6)H(4)PPh(2) (L)与过量十二烷基硫醇保护的金纳米粒子反应得到不对称金配合物[CH(3)(CH(2))(11)SAuPPh(2)C(6)H(4)COO(CH(2))(11)SH](4)，但没有形成膦保护的金纳米粒子。然而，通过用金属碎片阻断L中的磷化氢功能，我们已经能够通过配位交换反应的方法生产出具有AuCl-官能化的金纳米颗粒，并在表面聚集了[Fe(2)(CO)(7)Au]单元。
The reaction of the new ditopic thiol-phosphine compound HS(CH(2))(11)OOCC(6)H(4)PPh(2) (L) with an excess of dodecanethiol-protected gold nanoparticles gave the asymmetric gold complex [CH(3)(CH(2))(11)SAuPPh(2)C(6)H(4)COO(CH(2))(11)SH] (4), but no phosphine-protected gold nanoparticles were formed. However, by blocking the phosphine function in L with metal fragments, we have been able to produce gold nanoparticles functionalised with AuCl- and cluster [Fe(2)(CO)(7)Au] units on the surface by the method of ligand-place exchange reaction.
