Discotic liquid crystals of transition metal complexes 57†: X-ray diffraction halo jumps originated from sudden free rotation of substituent groups to induce mesomorphism

We have synthesized a novel series of four flying-seed-like liquid crystals (1Ph-PhO)4PcM [5-M: M = Co (5-Co), Ni (5-Ni), Cu (5-Cu) and Zn (5-Zn)] which are based on a phthalocyanine core having pe...
