| Abstract
| - We report the first example of a surface-confined two-step synthesis of axially coordinated metalloporphyrincomplexes in an ultrahigh vacuum environment. Specifically, a monolayer of tetraphenylporphyrin on anAg(111) surface was metalated with coadsorbed Zn atoms, and thereafter, NH3 ligands were attached to themetal centers. The surface reactions were monitored with X-ray photoelectron spectroscopy. The approachoutlined in this work can be employed to produce and study adsorbates of various axially coordinated porphyrincomplexes, including biologically relevant systems.
