Although metallophilic interactions, where metal d8 and d10 centers stack at less than van der Waals distances, have been noted in liquid crystalline phases, this type of interaction has not been systematically studied as a supramolecular ordering motif in liquid crystalline systems. A series of functionalized bipyrindine derivatives of Ag(I), Ni(II), Pt(II), and Pd(II) will be discussed in light of how metal-center selection and ligand functionalization affects the formation of metallophilic interactions. In some cases, room temperature metallomesogenic phases can be produced. Characterization of the complexes via X-ray diffraction, differential scanning calorimetry, and NMR spectroscopy will be presented. Additionally, a more efficient, less expensive, and more environmentally friendly mechanochemical synthetic method will be discussed.
