Cationic square planar Pt(II) complexes are reported with high degrees of intermolecular association. These complexes display thermotropic columnar liquid crystalline behavior in spite of having only a single side chain. Crystals undergo mechanochromic transformations that can be reversed with solvent.
报道了具有高度分子间缔合作用的阳离子四面体形 Pt(II) 配合物。这些配合物尽管只有一个侧链,但仍表现出热致柱状液晶行为。晶体经历机械变色转变,可通过溶剂进行反转。
