New molecular tweezers based on bis-Tröger’s base with methoxycarbonyl groups on its pincers was prepared. These groups were converted into hydroxymethyl groups, which were interconnected by a linker to give the bridged molecular tweezers, a cavitand. The cavitand was studied and its ability to bind nitrobenzene was compared with similar bis-Tröger’s base molecular tweezers.
