Crystalline/ionic liquid crystalline block
copolymers (BCPs) with various compositions have been successfully prepared by
sequential reactions. The effect of corona liquid crystalline order on self-assembly
of BCPs in selective solvent is investigated in detail. It is found that
twodimensional single crystals with well-developed shapes are formed when the liquid
crystalline order is present. By contrast, ill-developed platelets with small size
or one-dimensional worm-like micelles are assembled if the liquid crystalline
order of the corona segments is lost. It is speculated that the preferred
parallel arrangement of liquid crystalline block enables it to expose more
growth front of crystals. Accordingly, epitaxial crystallization will proceed readily,
leading to fabrication of the well-defined single crystals.
