Multicomb Polymeric Supramolecules and Their Self‐Organization: Combination of Coordination and Ionic Interactions

Abstract

Several alkyl side chains are bonded to each polymeric repeat unit using both coordinated ligands and electrostatically bound counterions to directly control the interface curvature of the self‐organized structures. 2,6‐Bis(octylaminomethyl)pyridine is Zn‐coordinated to poly(4‐vinylpyridine) (P4VP) with dodecylbenzenesulfonate (DBS) counterions, leading to multicomb polymeric supramolecules, poly[(4VP)Zn(2,6‐bis(octylaminomethyl)pyridine)(DBS)2]. Coordination is evidenced by infrared spectroscopy and visualized by quantum chemical calculations. The amorphous hexagonal self‐organized structures are characterized using X‐ray measurements. magnified image

Thermotropic Ionic Liquid Crystals via Self-Assembly of Cationic Hyperbranched Polypeptides and Anionic Surfactants

“…Supramolecular chemistry has been emerging during the past decade as an alternative route in which macromolecules of a certain complexity can be designed by assembling simpler building blocks which are held together by, e.g., hydrogen bonding or ionic interactions. [5][6][7][8][9] Not only does this technique offer the advantage to handle molecules and macromolecules of reduced complexity, but it also enables to exploit the reversibility of hydrogen or ionic bonds to control the morphology of segregated structures and allows the design of reversible or stimuli-responsive segregated nanostructures. 10,11 The hydrogen-bonding strategy has been applied mostly to linear homopolymers and block copolymers to design macromolecular templates in which the polymer backbone acts as a hydrogenbonding acceptor and surfactants act as hydrogen-bonding donors so that hairy comblike polymers are formed in which the segregation between the surfactant and the polymer backbone leads to the final morphology.…”

Self-assembled polymeric solid films with temperature-induced large and reversible photonic-bandgap switching

“…The poly(4-vinylpyridine) (P4VP) block of polystyrene-blockpoly(4-vinylpyridine) can selectively bond amphiphilic molecules by hydrogen bonding, coordination or ionic interaction allowing hierarchical structures and phase transitions 7,27,28 . Previously, it was observed that the comb-shaped architecture, formed by bonding dodecylbenzenesulphonic acid (DBSA) to the P4VP-block of PS-block-P4VP (where PS is polystyrene) caused large stretching of the chains thus leading to a visible bandgap 20 .…”

Transport and Electro‐Optical Properties in Polymeric Self‐Assembled Systems

“…blocks. The interactions can be ionic [43,[53][54][55][56][57][58][59][60][61][62][63][64][65][66], in which case the term ionic self-assembly can be used [42]; they can be hydrogen bonds or their combinations [10,11,21,22,34,; they can be coordinative [89][90][91][92][93]; or they can in principle be any sufficiently strong attractive interaction or their combination. Over the years, several examples have arisen of physical interactions that enable one to prepare polymer-like materials (Figs.…”
