合成了一种新型的双相液晶化合物八[3-（2-（2-（2-甲氧基乙氧基）乙氧基）乙氧基）苯氧基]酞菁铜（Ⅱ）（简称[m-MeO（EtO）3PhO] 8PcCu），并利用差示扫描量热仪、偏光显微镜和变温广角X射线衍射仪确定了其介晶性。非常有趣的是，该[m-MeO（EtO）3PhO] 8PcCu复合物在原始样品中显示出六方有序柱状（Colho）中间相，而在非原始样品中显示出矩形有序柱状（Colro（P21/a））中间相。Colhomophosphase的二聚体堆积距离为9.26 μ m，而Colromesophase的单体堆积距离较短，为3.45 μ m。此外，这种新的Pc衍生物容易溶于极性溶剂，如丙酮，乙醇和甲醇。利用本发明的亲水性[m-MeO（EtO）3PhO] 8PcCu衍生物在极性溶剂中的拮抗剂溶解度和先前的疏水性（C10O）16TzCu衍生物在非极性溶剂中的拮抗剂溶解度，可以成功地制备p-n结层状薄膜。
We synthesized a novel discotic liquid crystalline compound, octakis[3-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)phenoxy]phthalocyaninato copper(II) (abbreviated as [m-MeO(EtO)3PhO]8PcCu), and established the mesomorphism by using a differential scanning calorimeter, a polarizing optical microscope, and temperature-dependent wide angle X-ray diffraction diffractometer. Very interestingly, this [m-MeO(EtO)3PhO]8PcCu complex showed a hexagonal ordered columnar (Colho) mesophase in the virgin sample, whereas it showed a rectangular ordered columnar (Colro(P21/a)) mesophase in the non-virgin sample. The Colhomesophase gave a dimer stacking distance at 9.26 Å, whereas the Colromesophase gave a short monomer stacking distance at 3.45 Å. Furthermore, this novel Pc derivative is readily soluble in polar solvents such as acetone, ethanol and methanol. Using antagonist solubilities of the present hydrophilic [m-MeO(EtO)3PhO]8PcCu derivative in a polar solvent and the previous hydrophobic (C10O)16TzCu derivative in the non-polar solvent, a p-n junction layered thin films could be successfully prepared.
