Directing self-assembly in macromolecular systems: Hydrogen bonding in ordered polymers

Abstract: Hydrogen-bonded side-chain liquid-crystalline block copolymers (SCLCBCPs) containing block segments with proton donors were combined with functionalized mesogenic pendent groups. Studies of a wide range of mesogen and polymer combinations were carried out to study the relationship between morphology and mesophase behavior. The thermal behaviors of the resulting self-assembled microstructures were also examined. A model of the assembly process leading to mesogenic group organization corresponding to different compositions was proposed.

*Lecture presented at the symposium "Controlling the self assembly in macromolecular systems: From nature to chemistry to functional properties", as part of the 39th IUPAC Congress and 86th Conference of the Canadian Society for Chemistry: Chemistry at the Interfaces, Ottawa, Canada, 10-15 August 2003. Other Congress presentations are published in this issue, pp. 1295-1603.
