摘要:Iso-luminol functionalized gold nanomaterials were synthesized in high yield by a simple seeding approach, usingthe chemiluminescent reagent iso-luminol as reductant in the presence of HAuCl4, AgNO3and cetyltrimethylammoniumbromide (CTAB). The morphology of as-prepared gold nanoparticles was characterized by transmission electron microscopyand UV–vis spectroscopy, showing that gold nanotadpoles (AuNTps) were obtained. Subsequent experiments revealed thatthe amounts of seed colloids and AgNO3and the concentrations of iso-luminol and CTAB in the growth solution play criticalroles in the formation of well-shaped AuNTps. The surface state of AuNTps was characterized by UV–vis spectroscopy andfluorescence spectroscopy, indicating that iso-luminol and its oxidation product, 4-aminophthalate, coexisted on the surfaceof AuNTps. The CL behaviour was studied by static injection CL experiments, demonstrating that AuNTps were of CL activity.Finally, the growth mechanism of AuNTps was also discussed.
