TL;DR
This study examines how different alkyl substituents on thienylenevinylene oligomers affect their adsorption behavior on Si(100) surfaces, using STM to analyze configuration and image voltage dependence.
Contribution
It provides new insights into the role of alkyl chains in modulating oligomer adsorption and STM imaging on silicon surfaces.
Findings
Alkyl substitution significantly influences adsorption configurations.
The STM images of 3,4-dihexyl thiophene oligomers are highly voltage-dependent.
Alkyl chains affect both adsorption process and image appearance.
Abstract
The adsorption of thienylenevinylene oligomers on the Si(100) surface has been investigated using scanning tunneling microscopy. The mode of substitution of the thiophene ring exerts a strong influence on the adsorption configurations and the images of the oligomer based on 3,4-dihexyl thiophene are highly voltage dependent. We discuss the influence of the alkyl chains on the adsorption process and on the appearance of the molecules in the STM images.
