Ferroelectric metallomesogens composed of achiral spin crossover molecules.

ABSTRACT: Ferroelectric liquid crystals (FLCs) are fascinating functional materials that have a remnant and electrically invertible polarization. To date, typical FLCs have been mainly realized by molecular design such as the incorporation of chirality into a given molecular structure. Here, we report for the first time ferroelectricity induced by spin transition associated with a crystal - liquid crystal phase transition in achiral molecules. Iron(ii) metallomesogens incorporating alkyl chains of type [Fe(3C _n -bzimpy)₂](BF₄)₂ (n = 8 (1), 10 (2), 12 (3), 14 (4), 16 (5) and 18 (6); bzimpy = 2,6-bis(benzimidazol-2'-yl)pyridine) that exhibit spin crossover (SCO) phenomena have been synthesized.
