Modulating self-assembly and polymorph transitions in bisdendronized squaramides.

ABSTRACT: Supramolecular self-assembly is an advanced approach for constructing ordered nanoscale architectures with broad applications. While the principles of supramolecular polymerization have been thoroughly explored in artificial small molecules, polymer transformations remain barely explored, likely due to the lack of suitable reference models presenting well-defined and reversible transitions between aggregates. In this study, we introduce a series of bisdendronized squaramides (SQs) 1-3, showcasing complex self-assembly behaviours involving four distinct aggregates, three different interaction patterns, and various thermodynamically controlled polymorph transformations. Notably, SQ 3, with ethyl spacers between the SQ cores and the dendrons, exhibits a concentration and temperature-dependent
