Product Description of Ferrocenyl Alkanethiols
Ferrocenyl alkanethiols are utilized for the modification of gold surfaces to introduce electrochemically active molecules. The modified gold surface can be utilized for the development of sensitive electrochemical analyses. Rubin and others fabricated mixed SAMs of aminoalkanethiols and ferrocenyl alkanethiols with various chain lengths on a gold electrode surface. They immobilized glucose oxidase on aminoalkanethiol sites and used ferrocenyl-alkanethiol sites as electron mediators. They reported the relationship between electrical response and chain length of mixed SAMs. Uosaki and co-workers reported the results of structural changes and the number of absorbed ferrocenyl alkanethiols during redox reaction of 11-ferrocenyl-1-undecanethiol SAMs on a gold electrode using Fourier transform infrared reflection adsorption spectroscopy (FT-IRRAS) and electrochemical quartz crystal microbalance (EQCM) method. They suggested the possibility of orientation change of the monolayer during the redox reaction of the ferrocene moiety. They also estimated this change using voltammograms and ellipsometry.
