Conformational Control of Chemical Reactivity for Surface‐Confined Ru‐Porphyrins

چکیده
Abstract We assess the crucial role of tetrapyrrole flexibility in CO ligation to distinct Ru‐porphyrins supported on an atomistically well‐defined Ag(111) substrate. Our systematic real‐space visualisation and manipulation experiments with scanning tunnelling microscopy directly probe ligation, while bond‐resolving atomic force X‐ray standing‐wave measurements characterise geometry, ultraviolet photoelectron spectroscopy electronic structure, temperature‐programmed desorption binding strength. Density‐functional‐theory calculations provide additional insight into functional interface. unambiguously demonstrate that substituents regulate interfacial conformational adaptability, either promoting or obstructing uptake axial adducts.

متن کاملA Reactivity Based Emission Inventory for the South Pars and Its Implication for Ozone Pollution Control
The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to substantial ozone production downwind. To understand the role of these emissions on the ozone formation and, to formulate appropriate control st...
متن کاملSOLVENT EFFECTS AND CHEMICAL REACTIVITY Understanding Chemical Reactivity
This chapter reviews the theoretical background for continuum models of solvation, recent advances in their implementation, and illustrative examples of their use. Continuum models are the most efficient way to include condensed-phase effects into quantum mechanical calculations, and this is typically accomplished by the using self-consistent reaction field (SCRF) approach for the electrostatic...
