Dr. Ehesan Ali’s Theory and Simulations of Complex Materials (TSCM) laboratory in collaboration with Freie Universität Berlin, Germany and Uppsala University, Sweden observed a significant alternation of the magnetic properties of metalloporphyrin due to change of the macromolecule on the substrate.  They reported a substantial increase in the effective spin moment obtained from sum-rule analysis of X-ray magnetic circular dichroism (XMCD) for an iron metalloporphyrin molecule on Au(111) along with the on-site Coulomb correlation corrected density functional theory (DFT+U) through its conversion from Fe(II)-octaethylporphyrin (FeOEP) to Fe(II)-tetrabenzoporphyrin (FeTBP) in a surface-assisted ring-closure ligand reaction on Au(111)-substrate. This combined Computational and experimental work has been published in the Journal of Physical Chemistry C, 2009, 123, 14547.
