How to aggregate your domains : A method of forming tetrameric aggregates with an ααββ structure has been developed using stereoisomeric bidomain oligomers. Upon mixing the oligomers, a tetrameric ααββ aggregate was obtained by heteroaggregation at the ethynyl domain. The tetrameric aggregate reversibly changed its structure between the dimeric homoaggregates on heating and cooling, whereas gelation by polymerization occurred in toluene.
