Supplementary Figure 4: 1H NMR spectrum for compound 4
From: Preparative scale and convenient synthesis of a water-soluble, deep cavitand
1H-NMR spectrum (25 °C, DMSO-d6, 600 MHz) of the compound 4. The characteristic methine peak and the corresponding atoms are marked with the green arrows. The material usually contains residual solvents and salts that result in extra weighing but do not interfere with the next step.
