It is shown that the surface potentials of Langmuir monolayers from aromatic compounds can be interpreted using the three-layer capacitor model of Demchak and Fort, with the same local dielectric constants employed for aliphatic compounds. Based on new da

This paper is devoted to two new aromatic polyamines derived from p-EFTP (5'-(4-(bis(4-ethylphenyl)amino)phenyl-N,N,N',N'-tetrakis(4-ethylphenyl)-1,1':3',1"-terphenyl-4,4"-diamine) and exhibiting meta connections around a central phenylene ring.In p-EFDP (5'-phenyl-(N,N,N',N'-tetrakis(4-ethylphenyl)-1,1':3',1"-terphenyl-4,4"-diamine) there are only two redox sites instead of three.Upon partial oxidation, an intervalence transition is observed from which an electronic coupling very similar to the one of p-EFTP is obtained.In p-FADP (N,N,N',N',N",N"-hexakis(4-ethylphenyl)- 1,1':3',1"-terphenyl-4,4",5'-triamine) one finds two redox sites of the N,N'-bis(4-ethylphenyl)-4-aminobiphenyl type, and one redox site of the triphenylamine type.The analysis of the electrochemical behavior and of the intervalence transitions in the mono- and dioxidized species allows the distinction among the different types of electron transfer.

The formation of azo compounds via redox cross-coupling of nitroarenes and arylamines, challenging in solution phase chemistry, is achieved by on-surface chemistry. Reaction products are analyzed with a cryogenic scanning tunneling microscope (STM) and X-ray photoelectron spectroscopy (XPS). By using well-designed precursors containing both an amino and a nitro functionality, azo polymers are prepared on surface via highly efficient nitro-amino cross-coupling. Experiments conducted on other substrates and surface orientations reveal that the metal surface has a significant effect on the reaction efficiency. The reaction was further found to proceed from partially oxidized/reduced precursors in dimerization reactions, shedding light on the mechanism that was studied by DFT calculations.
