title: Switching the morphologies of cylindrical polycation brushes by ionic and supramolecular inclusion complexes.
abstract: Cylindrical polycation brushes form an ionic complex with surfactant sodium dodecyl sulfate (SDS) in aqueous solution, which causes a worm-to-sphere collapse of the brush. Alpha- and beta-cyclodextrin (CD) returns the brush to the worm-like conformation by forming a supramolecular inclusion complex with SDS. When beta-CD was employed for the inclusion complex, addition of 1-adamantylammonium chloride releases SDS by forming a stronger inclusion complex, causing the recollapse of the brush to spheres.
