Influence of the host–guest interactions on the ferroelectric properties of mononuclear orthopalladated metallomesogen mixtures

Abstract

A new series of four mononuclear orthopalladated complexes which contain a Schiff base and an aliphatic β-diketone as ligands is described. The miscibility of the modified complexes in a standard organic host material is improved in comparison with complexes studied previously. The increased solubility of the complexes leads to ferroelectric organometallic–organic mixtures with lower viscosities and switching times than purely organometallic mixtures, while the spontaneous polarization (P_s) values are maintained or increased.
