The synthesis, as well the mesomorphic and electrochemical properties, of a hetero-bimetallic coordination complex able to self-assemble into columnar liquid crystalline phase is reported herein. properties were investigated by polarized optical microscopy (POM), differential scanning calorimetry (DSC) Powder X-ray diffraction (PXRD) analysis. Electrochemical explored cyclic voltammetry (CV), relating behaviour previously analogous monometallic Zn(II) compounds. obtained results highlight...

Hetero-bimetallic liquid crystalline materials, exhibiting a single Colhex mesophase, were obtained by simple chemical blending between two structurally-related Cu(II) and Zn(II) metallomesogens based on 1,10-phenanthroline chelating gallate ligands. Mesomorphous optical properties modified upon their relative respective proportions. This study highlights the numerous possibilities for fabrication of new multifunctional polymetallic with possibility tuning controlling supramolecular...

New hetero-polynuclear coordination complexes based on pentacoordinated Zn(II) metal center with tridentate terpyridine-based ligands and monoanionic gallates functionalized long alkyl chains containing ferrocene units were designed, synthesized characterized by spectroscopic analytical methods. The are mesomorphic, exhibiting columnar hexagonal mesophases at room temperature. photophysical properties in solution accurately investigated the influence of polarity media was evidenced.

The present paper describes the preparation and characterization of a new dinuclear ligand based on terpyridine featuring diselenide unit. This compound was synthesized in two-step procedure that first involved insertion moiety carboxylic acid followed by Steglich esterification reaction between biscarboxylic containing unit 2,6-di(pyridin-2-yl)pyridin-4-ol (tpyOH). title characterized via FT-IR, Raman, NMR (1D 2D), UV-Vis spectroscopies elemental analysis. Emission properties were investigated.
