The design and synthesis of tripodal 1,3,5-R-2,4,6-R?-benzene tris-disulfides (R = Et, R? = phenyl or alkyl) is reported. These multi-armed systems were employed in the stable capping of colloidal AuNPs, allowing control of the ratio between the benzene core and peripheral moieties. These systems were shown to act as sensing nanomaterials for nitro aromatic explosives.

Abstract
The design and synthesis of tripodal 1,3,5-R-2,4,6-R?-benzene tris-disulfides (R = Et, R? = phenyl or alkyl) is reported. These multi-armed systems were employed in the stable capping of colloidal AuNPs, allowing control of the ratio between the benzene core and peripheral moieties. These systems were shown to act as sensing nanomaterials for nitro aromatic explosives.File in questo prodotto:
