Abstract
U ovom radu istražen je utjecaj strukture adsorbata, vremena na koje je supstrat uronjen u otopinu adsorbata te koncentracije otopine na stvaranje samoudruženih monomolekulskih i bimolekulskih slojeva derivata nitrozobenzena na površini zlata (111). U tu svrhu pripravljena su tri derivata nitrozobenzena koji su u para-položaju obzirom na nitrozo skupinu supstituirani alkilnim lancima različitih duljina na čijim se krajevima nalaze tiocijanatne skupine. Samoudruženi molekulski slojevi priređeni su adsorpcijom derivata nitrozobenzena na površinu zlata (111) preko atoma sumpora. Prosječne debljine molekulskih slojeva derivata nitrozobenzena na zlatu te njihova ovisnost o strukturi adsorbata i eksperimentalnim uvjetima priprave slojeva istražene su pomoću elipsometrije. Rezultati ovog rada ukazuju da sposobnost formiranja samoudruženih bimolekulskih slojeva derivata nitrozobenzena s kraćim alkilnim lancima raste s vremenom na koje je supstrat zlata uronjen u otopinu spoja te s povećanjem koncentracije otopine.
Abstract (english)
The influence of the adsorbate structure, the adsorption time and the concentration of the solution on the formation of self-assembled mono- and bilayers of nitrosobenzene derivatives on gold (111) surface was investigated. For that purpose, three nitrosobenzene derivatives substituted with thiocyanate-ended alkyl chains of different lengths in a para-position relative to the nitroso group were synthesized. Self-assembled layers were prepared by adsorption of nitrosobenzene derivatives on the gold surface through the sulphur atom. The average thicknesses of the molecular layers of nitrosobenzene derivatives and their dependence on the adsorbate structure and experimental conditions of layer preparation were studied by ellipsometry. The results of this work indicate that the ability of nitrosobenzene derivatives with shorter alkyl chains to form self-assembled bilayers increases with the adsorption time and with the increase of the concentration of the solution.
