The synthesis, characterization and liquid crystalline properties of N4,N40-bis((1 H-benzo[d]imidazol-2-
yl)methyl)-3,30-dimethyl-[1,10-biphenyl]-4,40-diamine and of their corresponding Mn(II), Fe(II), Ni (II),
Cu(II), and Zn(II) complexes are described. The ligand and complexes have been characterized by elemental
analysis, magnetic susceptibility measurements (meff), conductometric measurements and Fourier
Transform Infrared (FTIR), Nuclear Magnetic Resonance (1H NMR), (13C-NMR) and UV–Vis spectroscopy.
Spectral investigations suggested octahedral coordination geometrical arrangement for M(II) complexes.
The phase transition temperatures were detected by differential scanning calorimetry (DSC) analysis and
the phases are confirmed by op
