摘要：
CO2-philicity: The 13C NMR chemical shift (δc) of supercritical CO2 containing carbonyl compounds moves to lower fields with increasing CO2 density in parallel with the δc value of neat ScCO2. The difference in the magnitude of these shifts (Δδc) is attributed to the strength of solute-CO2 interactions (see picture, R = CH3 or CF3, L = DMSO) and allows determination of the CO2-philicity of solute molecules in ScCO2.
