  新型介晶八烷基（烷硫基）取代的酞菁铅及其薄膜的合成与表征

  摘要：

  描述了Pb（II）（1a和2a）的新的辛基（烷硫基）取代的酞菁的合成。这些化合物非常易溶于大多数常见的有机溶剂。使用元素分析，NMR，红外和UV-Vis光谱对它们进行了充分表征。通过差示扫描量热法和光学显微镜研究了这些新材料的介晶性能。这些酞菁衍生物在室温下为液体，并在低于-10°C时形成柱状六方（Col h）中间相。已经表明，在酞菁（Pc）核上添加亚甲基桥会增加清除点温度。另外，Pb 2+的配位与酞菁核一起使用会降低透明点温度和液晶相变温度。通过旋涂法制备八（烷硫基）取代的Pb（II）酞菁酞菁薄膜1a和2a。为了获得具有有序结构的膜，将1a的膜从室温缓慢冷却至-10℃。准备用于研究其电性能的Au / PbPc（1a）/ Au形式的三明治结构。结果表明，缓慢冷却的Au / PbPc（1a）/ Au结构在-1 V至+1 V之间施加的偏置电压下表现出可重复且稳定的电开关性能。

  Methylene-bridged tetra- and octa-(13,17-dioxa nonacosane-15 sulfanyl)-substituted metal free- and Ni(II) phthalocyanines were synthesized from the corresponding phthalonitrile (3, 4) derivatives in the presence of the anhydrous metal salt (NiCl2) or a strong organic base. The new compounds were characterized by elemental analyses, UV/Vis, IR, NMR and mass spectra. The mesogenic properties of these materials were studied by differential scanning calorimetry (DSC), optical microscopy and X-ray diffraction investigations. X-ray diffraction patterns of the mesophase confirm that tetra- and octa-substituted compounds (3a-b, 4a-b) form hexagonal columnar mesophases (Col(h)). We indicated that addition of the methylene-bridged phthalocyanine (Pc) core can either decrease the liquid crystal phase transition temperatures or extend the liquid crystal temperature range to include room temperature. Also, the Pc compounds (3a, 3b, 4a and 4b) are liquid crystals at room temperature. These properties of the Pc complexes provide some advantages such as easily obtaining an ordered film for sensor applications. Computational modelling work was combined with X-ray diffraction investigation to validate the diameter of the phthalocyanine molecule (3b). (c) 2006 Elsevier Ltd. All rights reserved.
