Molecular ferroelectric thin films and block crystals along crystal face (10) of imidazolium perchlorate display perfect hexagonal domains similar to that of the trigonal crystal system LiNbO3. The high spontaneous polarization, high Curie temperature, low coercivity, and superior electromechanical coupling make it a molecular alternative to perovskite ferroelectric films.
