Sažetak
In the present study, we investigated nitrosoarene dimerization on an Au(111) and on the surface
of gold nanoparticles (AuNPs). High-resolution STM images revealed that 8-thiocyanatooctyl-4-
nitrosobenzoate (NCS(CH2)8OOCC6H4NO) forms well-ordered monolayer on an Au(111) surface displaying
hexagonal 3 3 3 3 structure. AFM data indicated that this compound also dimerize on an Au(111)
surface thus forming bilayers. On contrary, adsorption of 6-(4-nitrosophenoxy)hexane-1-thiol
(HS(CH2)6OC6H4NO) on an Au(111) leads only to poorly organized monolayer.
Furthermore, it was found that nitrosoarene derivatives 8-thiocyanatooctyl-4-nitrosobenzoate
(NCS(CH2)8OOCC6H4NO) and 3-thiocyanatopropyl-4-nitrosobenzoate (NCS(CH2)3OOCC6H4NO) are
present as dimers on the surface of AuNPs. There is no appreciable quantity of dimeric species with free
thiocyanate termini indicating interlinkage of AuNPs through azodioxide bonds. Besides the characteristic
surface plasmon band, UV-vis spectra showed an additional red-shifted band that might have origin in
aggregation of AuNPs. This was further supported by TEM revealing the appearence of larger aggregates
in addition to smaller AuNPs.(doi: 10.5562/cca2023)
