Molecular and electronic structure of osmium complexes confined to Au(111) surfaces using a self-assembled molecular bridge
The molecular and electronic structure of Os(II) complexes covalently bonded to self-assembled monolayers (SAMs) on Au(111) surfaces was studied by means of polarization modulation infrared reflection absorption spectroscopy, photoelectron spectroscopies, scanning tunneling microscopy, scanning tunn...
