3. Molecular tweezers are a type of host-guest supramolecular assembly. They generally consist of two interaction sites linked by a spacer. The identity of the interaction site determines what will be bound as a guest. (a) From you understanding of non-covalent interactions, design a suitable molecular tweezer, explaining your choice, for: i. The removal of benzene from water ii. The isolation of potassium from solution. $$\text{ (2 }25\text{ Marks) }$$ (b) Describe TWO published applications of molecular tweezers. Your answer should include a detailed description of the synthesis of said tweezer, self-assembly process with a guest, analysis and potential disadvantages (20 Marks)
