| 中文摘要 | in the present work, we have studied the aggregation of gold nanoparticles (au-nps) induced by a cationic perylene probe (compound 1). the compound 1 free monomer contains a large planar aromatic ring structure that could be efficiently adsorbed onto the surface of the au-nps. the strong pi-pi stacking and hydrophobic interactions among compound 1 probe molecules adsorbed on adjacent nanoparticles, and the neutralization of the au-np surface citrate ion negative charges induced rapid aggregation of the au-nps, and evident uv-vis spectra and solution color changes. the use of this observation for a label-free selective sensing of mercury ion has been demonstrated. |
