We have recently developed a method to prepare a wide variety of amphiphilic diblock copolymers through a supramolecular linkage that is stable in water. This has been achieved through the use of a macrocyclic host molecule cucurbit[8]uril (CB[8]) capable of complexing two guest molecules simultaneously forming a ternary complex with a Ka on the order of 1015 M-1. Upon mixing, the two homopolymers bearing the selective endgroups with CB[8], an AB diblock copolymer is formed which can undergo further self assembly into a variety of compartmentalised structures, such as spherical and cylindrical micelles and vesicles. The formation of a specific structure as well as its overall size can be easily controlled by the ratio of the two homopolymers and we aim to study the architectural details of a range of achievable structures via SANS, using deuterated versions of the hydrophobic block.
