A nonequilibrium Green’s function approach based on self-energy corrected density functional theory and optimally tuned range-separated hybrid functionals is developed and used to understand experimental trends quantitatively. Importantly, due to the localized d states of the porphyrin molecules, hybrid functionals are essential for explaining measurements; standard semilocal functionals yield qualitatively incorrect results. Comparing directly with experiments, we show that the conductance can change by nearly a factor of 2 when different metal cations are used, counter to trends expected from gas-phase ionization energies which are relatively unchanged with the metal center. Our work explains the sensitivity of the porphyrin conductance with the metal center via a detailed and quantitative portrait of the interface electronic structure and provides a new framework for understanding transport quantitatively in complex junctions involving molecules with localized d states of relevance to light harvesting and energy conversion."}],"date_created":"2024-09-09T10:57:42Z","day":"11","OA_type":"closed access","citation":{"mla":"Liu, Zhen-Fei, et al. “Control of Single-Molecule Junction Conductance of Porphyrins via a Transition-Metal Center.” Nano Letters, vol. 14, no. 9, American Chemical Society, 2014, pp. 5365–70, doi:10.1021/nl5025062.","ieee":"Z.-F.
