Controlled Architecture of Dendritic Subphthalocyanine Arrays to Explore Cooperative Effects of Its Hierarchical Chirality

本研究利用氯-苯氧基取代法制备多亚酞菁阵列，探讨其结构和物理性质。一个六聚亚酞菁阵列已成功地引入到六（4-羟基苯基）苯核，尽管它是多个反应位点与过度的空间位阻。六聚体阵列显示出减色性，并在极性溶剂中形成非荧光激基缔合物。为了构建自支化亚酞菁阵列作为螺旋手性单元，人们尝试拆分对映体混合物。然而，本研究中合成的单体亚酞菁溶解性和稳定性差的缺点难以克服。最终，自支化亚酞菁阵列甚至作为对映体混合物得到。自分支阵列的特性鉴定正在进行中。

The present study performed multi-subphthalocyanine arrays by using chlorine-to-phenoxy substitution to explore the structural and photophysical properties. A hexameric subphthalocyanine array has been successfully introduced into a hexakis (4-hydroxyphenyl) benzene core despite it being multiple reaction sites with excessive steric hindrance. The hexameric array shows hypochromism and forms non-fluorescent excimer in polar solvents. To construct self-branching subphthalocyanine arrays as a spiral chiral unit, it had been attempted to resolve the enantiomeric mixture. However, it was difficult to overcome the poor solubility and stability of the monomeric subphthalocyanine synthesized in this study. Eventually, the self-branching subphthalocyanine arrays have been obtained even as the enantiomeric mixture. Characterization of the self-branching arrays is ongoing.
