ABSTRACT

Using the cyclometallation reaction, Pt(II) complexes of diarylbipyridynic ligands bearing alkoxy-groups were prepared and then modified with phenylаcetylene derivatives. The target compounds were characterised by absorption and emission spectroscopy, differential scanning calorimetry, small angle X-ray scattering, polarisation microscopy, and DTF calculations. The mesomorphic properties of the obtained compounds were investigated and their liquid crystallinity was confirmed.
