Scanning tunnelling microscopy (STM) has been used to obtain images, in ultra-high vacuum (UHV), of molecules of eta 5-cyclopentadienyl-bis triphenylphosphine ruthenium 4-pentaoxybenzonitrile hexafluorophosphate (Ru* complex) and a monolayer of polymerized polydiacetylene (PDA) deposited on Au substrates in the form of Langmuir-Blodgett films. Tunnelling spectroscopy has been used to detect the electronic structure on the surface due to Ru* complex molecules. Ultraviolet photoelectron spectroscopy (UPS) was used to confirm this electronic structure.
