Conjugated polymers quinoidal resonance structures

Subsequently, small-band gap LC conjugated polymers [11] based on benzonoid and quinoid resonance structures were synthesized. Subsequently, ferroelectric LC (FLC) conjugated polymers [12] consisting of acetylene, thiophene, phenylene, or phenylenevinylene unit cell were synthesized in order to achieve highly quick response to an electric force field during macroscopic alignment. These FLC conjugated polymers, however, will not be further mentioned here and reviewed elsewhere.
