Azo tether: Molecular films obtained by electrochemical reduction of diazonium tetrafluoroborate salts of 4-carboxy benzene and 4-amino-(2,3,5,6-tetrafluoro)-carboxy benzene on Au substrates are studied by a combination of X-ray photoelectron and polarization-modulation infrared reflection absorption spectroscopy. The spectroscopic evidence demonstrates the formation of N[DOUBLE BOND]N bonds tethering the complexes to Au (see picture).
