| Research Abstract |
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.
