The molecular symmetry of all the existing organic ferroelectrics was analyzed with an intention to develop a criterion to search for new low molecular weight organic ferroelectric. We present here a summery of the analysis; it is conclude that in order to exhibit ferroelectricity in crystalline state the molecules should necessarily poses symmetry higher than C 1 , since this appears to be an important requirement to ensure reorientability of the electrical polarization of the crystals.
