ABSTRACT
An isomer of tetracyanoporphyrinquinodimethane (TCPQ), 5,10-TCPQ, was designed, synthesized, and structurally characterized, and its basic properties were discussed with emphasis on comparison with those of reported 5,15-TCPQ. The title compound was synthesized by a convenient cascade reaction involving a catalyst-free aromatic nucleophilic substitution reaction and the Uno-Takahashi reaction. The obtained π-expanded redox molecule acted as a Wurster-type redox molecule that underwent not only reduction but also oxidation processes. Furthermore, its absorption spectrum showed a large bathochromic shift that extended to the near-IR region, approximately 1150â nm.
