摘要：
Organo-soluble tetraphenylethylene derived monolayer-protected gold nanorods were prepared and characterized. The prepared gold nanorods covered with tetraphenylethylene thiol via the strong covalent Au-S linkage were found to be soluble and stable in organic solvents. The successful thiol exchange and modification of tetraphenylethylene derivative molecules on gold nanorods were confirmed from UV-Vis, Raman and FT-IR spectra. The gold nanorods were found to have a quenching effect on the aggregation-induced emission of the tetraphenylethylene thiol molecule modified on their surfaces. (C) 2015 Elsevier Ltd.
