Through rational molecular design and modulation of side chain composition of the copolymers
as an efficient approach
it is quite efficient to achieve diverse phase transition behaviours and adjust phase structures.
A series of novel side-chain liquid crystalline (SCLC) copolymers were synthesized by attaching two distinct mesogenic units
namely a chiral cholesteryl-based monomer (M1) and an achiral biphenyl-based monomer (M2)
to a poly(3-mercaptopropylmethylsiloxane) (PMMS) backbone
via
thiol-ene click chemistry. The influence of side chain composition on the self-assembly behavior and phase structures of these SCLC copolymers was systematically investigated using different instrument. Results indicate that three distinct liquid crysta
lline phases and four unique molecular configurations were identified within the polymer series
with the emergence of the liquid crystalline phase being a synergistic outcome of the two distinct side chains. This study underscores the critical influence of side chain dimensions
rigidity
and spatial volume on the self-assembly structures and phase characteristics of liquid crystalline polymers
providing valuable insights for the rational design and development of advanced functional materials with tailored properties.
