Typical examples of rod-coil molecules
have dealt more with the phase behavior of rod-coil diblocks in a selective
solvent for the coil segment [28]. These works have predicted various micel-
lar structures for sufficiently large coil volume fractions, in addition to the
familiar lamellar structures.
This chapter will present an overview of recent work in designing rod-
coil systems, demonstrating their self-organization capability into a variety of
liquid crystalline phases.

Rod-Coil Diblock Copolymers Based on Perfectly Monodisperse Rods
It is well known that the connection of oligo(alkylene ether) chains into
a calamitic rigid rod at the terminals destabilizes the thermotropic meso-
phases [8]. However, mesomorphic properties can be obtained by molecules
with extended rigid rod segments as a result of the microphase segregation
between the polar flexible oligo(alkylene oxide) ethers and rigid rod seg-
