  摘要：

  Isothiouronium-modified gold nanoparticles 1 with an average diameter of 5.8 run were synthesized from bis(5-(N,N'-dimethyl-S-isothiouronio)pentyl) disulfide 2. The surface plasmon band at 524 nm in 10% (v/v) H2O-MeOH showed a selective red shift upon adding anions, making this potentially useful as a new anion sensor material. (c) 2005 Elsevier Ltd.

  Gold nanoparticles modified with isothiouronium-derived amphiphile units 1 were prepared by the reduction of AuCl4- (n-C8H17)(4)N+ with NaBH4 in the presence of bis(5-(N-(2-(2-methoxyethoxy)ethyl)-N-methyl-S-isothiouronio)pentyl) disulfide 2. The obtained rianoparticles 1 showed a selective coloration for hydrophobic anions in water, possibly due to an anion exchange and subsequent aggregation. Oil the basis of this observation, the detection of F- in water has been achieved using 3-nitrophenylboronic acid as a mediator at pH 5.5, thereby providing a new strategy for the design of a F- sensory system.
