Halogen-bond-driven supramolecular assemblies of quaternary-ammonium-iodide-containing polymers in three phases

Halogen bonding (XB) opens avenues to supramolecular assemblies. Here, we report XB-driven assemblies of quaternary ammonium iodide (QAI)-containing polymers in three (solution, surface, and solid) phases. In the solution, QAI-containing block copolymers form unique self-assembly structures such as micrometer-sized giant vesicles (up 5-μm diameter) a 1-dimensional (1D) structure with multiple inter-vesicular linkages via XB. Exploiting temperature dependence XB strength, external molecules are successfully loaded unloaded. On reversible crosslinking decrosslinking polymer brushes achieved. The wettability brush is finely tuned by density. solid phase, monomers co-crystalized (assembled) A sheet obtained solid-phase polymerization monomer co-crystal; enables capture release halogen-containing (XB-coordinating) guest thereby serves an innovative host material.
