    Cyclopropane as an Unsaturation “Effect Isostere”: Lowering the Melting Points in Lipid-like Ionic Liquids by Richard A. O’Brien (1538818)

    Published 2023
    “…Inspired by this phenomenon, we herein address the relative effect of the cyclopropanation, both <i>cis</i> and <i>trans</i> configurations, on melting points, packing efficiency, and order of a series of lipid-like ionic liquids via a combination of thermophysical analysis, X-ray crystallography, and computational modeling. …”

    Coumarin-Annelated Regioisomeric Heptahelicenes: Influence of Helicity on Excited-State Properties and Chiroptical Properties by Arindam Mukhopadhyay (1961227)

    Published 2019
    “…Two regioisomeric pairs of heptahelical mono- and biscoumarins that are differentiated by “<i>inward</i>” and “<i>outward</i>” disposition of the pyran-2-one moiety have been synthesized and investigated to understand the influence of helicity on excited-state and chiroptical properties. A slight variation in the helicities is found to manifest in contrasting excited-state properties of coumarin-annelated heptahelicenes; in addition to the intramolecular charge transfer, structural relaxation in the excited state is shown from theoretical calculations to cause decrease in the fluorescence quantum yield for a system with higher helicity. …”
