We have synthesized a range of block and star-block copolymers with stimulus-responsive components that are capable of forming different types of assemblies under different conditions. We have investigated a range of synthetic systems designed to assemble in water into smaller micellar aggregates at low temperatures and larger vesicles at higher temperatures. The structural shifts shown by several systems, including responsive amphiphilic triblock copolymers and ABC star-arm star copolymers, under specific conditions will be discussed. A number of factors, including block size and extent of interblock interactions, appear to be important in controlling transformation rate. Efforts made to understand these effects will also be described.
