In this work, we present a new approach for development of metallomesogen (MOM) mixtures for potential applications in electrooptical devices. Through combination of molecular engineering and physical mixing technique, we propose to overcome the major drawbacks of MOMs, including their inaccessible transition temperature and low solubility in liquid crystal hosts. In the present study, we report on the miscibility of bi-ligand Cu, Ni and Pd complex salicylal-diaminates metallomesogens as model structures. Accordingly, we studied the phase diagrams of two binary MOM mixtures with different metals and ligands. The preliminary results indicate the complete mesogenic miscibility, distinct eutectic points and wide mesogenic range, which provide as model materials in electro-optical devices.
