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.
