On December 5, 2020, Shumbula, Ndivhuwo P.; Ndala, Zakhele B.; Nkabinde, Siyabonga S.; Kolokoto, Tshwarela; Shumbula, Poslet M.; Mdluli, Phumlani S.; Hlatshwayo, Thulani; Mlambo, Mbuso; Moloto, Nosipho published an article.Name: 1-Decanethiol The title of the article was Experimental and theoretical studies of 1-alkanethiols SAMs of various chain-lengths on gold nanoparticles and their effect on SERS, stability and surface properties. And the article contained the following:
1-Alkanethiol SAMs on AuNPs have shown great potential towards the development of new functional materials. This is mainly due to the formation of dense, tightly bonded and well-ordered systems on the surface of AuNPs. This work showcases how the chain-length of 1-alkanethiols affects the stability and surface properties of AuNPs and the SERS effect. Using exptl. and theor. studies (by means of DFT), this work shows the interaction between 1-alkanethiols of 3 different chain-lengths and AuNPs. The effects on the optical properties, surface charge, stability and SERS were also investigated. The red shift of surface plasmon resonance band was observed as a result of the interaction between AuNPs and 1-alkanethioals. The Zeta potential indicated a strong electrostatic repulsion between AuNPs which was reduced after functionalizing with 1-alkanethiols. The long chain alkanethiol was found to strongly reduce the surface charge due to strong interaction with AuNPs. The calculated nucleophilic center cross-sections for all alkanethiols were found to increase with the chain-length, indicating a strong interaction existed between long chain alkanethiol and AuNPs. The SERS data shows an increase in Raman intensities of all 1-alkanethiols adsorbed on the surface of AuNPs. Both the exptl. and theor. data shows that the alkanethiol with short chain-length possesses the strongest Raman signal enhancement. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Name: 1-Decanethiol
