Triply Linked Porphyrinoids.

Tanaka, Takayuki; Osuka, Atsuhiro

Triply linked porphyrin arrays, so called porphyrin tapes, are intriguing molecules in terms of their planar structures, far red‐shifted absorption bands, multi‐charge storage abilities, and high conductivities. Recently, porphyrin tape variants such as porphyrin‐expanded porphyrin hybrid tapes, porphyrin arch‐tapes, corrole tapes, and a subporphyrin tape have been explored as novel π‐conjugated materials. These new molecules exhibit electronic and structural characteristics owing to direct triple linkages. This Minireview first discusses the fundamental properties of the parent porphyrin tapes and the peripherally functionalized porphyrin tapes. Then, a focus has been placed on the syntheses, structures, and unique properties of the recently explored porphyrin tape variants. The best things come in threes: Triply linked porphyrin arrays, so called porphyrin tapes, are intriguing molecules in terms of their stability, far red‐shifted absorption band, multi‐charge storage ability, and conductivity. Recent advances in the chemistry of porphyrin tape are summarized in this Minireview, in particular, the development of porphyrin tape variants such as expanded porphyrin hybrid tape, porphyrin arch‐tape, corrole tape, and subporphyrin tape.
