These differences in solubility may be of importance when considering the LLPS process in secondary organic aerosol as well. Oligomeric species in SOA particles have been cited to be active in the LLPS process-during which lower volatility, hydrophobic organic species separate from the bulk to create an organic shell-like morphology around an aqueous core. Future work is needed to examine the effects of backbone stereochemistry on the LLPS of atmospherically-relevant oligomers like those studied here. We do note that on average, the logKOAS values are slightly more negative than the logKOW values, an unexpected result based on the observed decreased solubility in ammonium sulfate solution. However, this difference is much smaller than the thermal energy at 300K, and therefore not an issue of significance.
