Lars' study introduces seven new ferrocenyl-modified N,N′,N″-triethyltriazatruxenes (EtTATs) and a dodecyl counterpart, demonstrating their utility as molecular switching units on an Ag(111) surface. These compounds offer a promising avenue for high-density information storage and processing. Voltammetric studies reveal that the ferrocenyl residues of these compounds oxidize prior to the TAT core, leading to multiple electronic excitations in the near-infrared and visible spectra. EtTAT and its derivatives are identified as directional three-level switching units, but symmetrical trisubstitution slightly reduces their switching rates due to interactions with the Ag surface. Unsymmetrical substitution in mono- and diferrocenylated derivatives alters the switching behavior, showcasing the potential of ferrocenyl-modified EtTATs for molecular information storage and processing.
