Supplementary Figure 7: 1H NMR spectrum for compound 6 lyophilized
From: Preparative scale and convenient synthesis of a water-soluble, deep cavitand
1H-NMR spectrum (25 °C, DMSO-d6, 600 MHz) of the compound 6 after lyophilization. The characteristic methine peak and the corresponding atoms are marked with the green arrows. Lyophilzation efficiently removes acetone traces.
