Low-symmetry, adjacent-type metallophthalocyanines 1 and 2 with four branched alkyl chains on one side and a chiral bridging segment on the other were synthesized, and their self-organization properties were investigated. The synthesized adjacent-type phthalocyanines were liquid-crystalline and exhibited a phase transition from the crystalline phase to the mesophase below room temperature. X-ray diffraction indicated that the molecules are stacked in one-dimensional columnar aggregates with a hexagonal arrangement. The self-organization behavior of zinc complex 1 and cobalt complex 2 was also investigated with a monolayer experiment at the air-water interface. The adjacent-type phthalocyanines formed a stable monolayer at the air-water interface, and the monolayers could be transferred onto quartz substrates by a Y-type deposition. UV-vis, XRD, and CD measurements for the resulting Langmuir-Blodgett films indicated that 1 and 2 had different molecular orientations.
合成了一侧带有四条支链烷基链而另一侧带有手性桥接片段的低对称性邻位型金属酞菁1和2，并研究了它们的自组装性质。合成的邻位型酞菁呈液晶态，在室温以下表现出从晶相到中间相的相变。X射线衍射表明，分子以六方排列堆积成一维柱状聚集体。还通过气-水界面的单层实验研究了锌配合物1和钴配合物2的自组装行为。邻位型酞菁在气-水界面形成了稳定的单层，并且这些单层可以通过Y型沉积转移到石英基板上。对所得朗缪尔-布洛杰特膜的紫外-可见、X射线衍射和圆二色测量表明，1和2具有不同的分子取向。
