High-pressure computational organic chemistry
Pressure is as fundamental as temperature to chemical reactivity. Understanding and controlling organic reactivity under pressure is essential in many areas of high-pressure research and industry, such as the Haber-Bosch process for nitrogen fixation (0.1 kbar; 1 kbar ≈ 1000 atm), prebiotic chemistry under pressure (<1 kbar), diamond synthesis (60 kbar), nanothread synthesis (200 kbar), and organic superconductor formation (>1000 kbar). A challenge in the computational study of high-pressure reactions is to properly incorporate the effect of pressure in electronic structure calculations. The recently developed eXtreme Pressure-Polarizable Continuum Model (XP-PCM) introduces pressure in the calculation of solvated molecular systems by constraining the accessible space of the molecule’s electrons with a density-dependent repulsive potential around the molecule. The effect of pressure is modeled as a simultaneous increase in the Pauli repulsion between the molecule and the medium and a decrease in the volume of the cavity that accommodates the molecule.

Exploring organic chemistry under pressure with computations The research group of Bo Chen (https://bochengroup.xyz) at the Donostia International Physics Center in San Sebastian, Spain, is looking for one motivated Ph.D. student to join the group in fall 2021.
The goal of the project is to develop the field of computational high-pressure organic chemistry. The candidate is expected to work on improving/developing two original computational methods-—the eXtreme Pressure Polarizable Continuum Model (XP-PCM) and the Helium Compression Chamber (HCC) model-–to allow for first-principles calculations to be performed on organic systems under high pressure. In addition, the candidate is expected to apply the above two computational methods to the investigations of the validity of Woodward-Hoffmann rules under high pressure and the effect of pressure on stereoselectivity in organocatalysis.
