Phenanthroline Ligands

Molecular electrostatic potential analysis of substituent effects in phenanthroline ligands clearly suggests that the coordination strength of the ligand to a metal complex is highly predictable solely from the quantification of substituent effects.

The present scientific contribution aims to investigate computationally the effects of substitution and substituent position on the reactivity of a series of salicylideneaniline derivatives ligands containing 13 molecules. Global reactivity parameters such as the EHOMO, ELUMO, gap energy, electronegativity, chemical hardness, chemical softness, electrophilicity index, and molecular electrostatic potential analysis (MESP) have been calculated at DFT/B3LYP/TZP level of theory and then well discussed to give valuable explanations for the effects of substitution and substituent position on the reactivity of the studied ligands.
