Ferroelectric liquid crystalline conjugated polymer with small-bandgap - Synthesis and properties of poly(pyrrylenemethine) derivative
Novel ferroelectric liquid crystalline (FLC) pi -conjugated polymer with small-bandgap was synthesized. The polymer consists of benzenoid and quinonoid structures of pyrrole and methine moiety substituted with FLC group. The polymer exhibits Sc* phase and has a bandgap of 2.1 eV. The spontaneous polarization of the polymer is evaluated to be 118 nC/cm(2).
