Abstract
- In this work, a novel compound 2‐(3,5,6‐trichloro‐1,4‐benzoquinon‐2‐yl)‐neo‐fused hexaphyrin has been prepared from tetrachloroquinone and neo‐fused hexaphyrin through a substitution reaction. The chemical structure of the compound has been characterized by nuclear magnetic resonance (NMR), high‐resolution mass spectrum, UV–Vis spectrum, and X‐ray diffraction. The crystal structure reveals that the quinonyl unit is almost coplanar with the adjacent N‐confused pyrrole unit. Because of the cooperative effect of extended conjugation and the intramolecular charge transfer effect related to the strong electron‐withdrawing character of the quinonyl unit, the absorption of 2 is dramatically extended to ca. 1280 nm.
