About the Book

Films comprising gold nanoparticles (NPs) linked with 1-(hexanethiol)-1'-(ethanethiol) ferrocene (FDT) were self-assembled layer-by-layer on gold electrodes and aminosilane-functionalized glass slides. Reflection-Absorption Fourier Transform Infrared Spectroscopy (RAIRS) and Ultraviolet-visible Spectroscopy (UV-Vis) were used to confirm self-assembly, and Cyclic Voltammetry (CV) was used to monitor redox peaks following self-assembly of each FDT and NP layer. Addition of a NP layer consistently resulted in a significant decrease in redox peak height, while addition of a subsequent FDT layer resulted in a net overall increase. Occasionally, redox activity dropped substantially but recovered with increasing number of NP-FDT exposure. All samples exhibited an increase in redox peak width and a slight increase in peak separation with increasing FDT-linked NP film thickness for the first 4-5 layers. No systematic trend was observed from sample to sample for subsequent layers. These results suggest that a disordered, porous film structure is formed by the self-assembly process.
