摘要: Abstract The synthesis of three differently substituted bis(octaalkyloxyphthalocyaninato) lutetium complexes and their chemically oxidized hexachloroantimonate derivatives is described. Their thermotropic polymorphism studied using polarizing microscopy, differential scanning calorimetry, X-ray diffraction. A tentative model describing the columnar (discotic) structure one observed mesophases proposed. magnetic behavior neutral has been determined by ESR as a function temperature, showing presence spin per molecule. structural transitions are associated with change shape width signal.
