Porphycen, entdeckt von Emanuel Vogel, war das erste vollständig charakterisierte Porphyrinisomer. Anders als für die Porphyrine sind Studien zu expandierten Porphycen‐Gerüsten rar geblieben. In ihrer Zuschrift auf S. 2605 wagen J. L. Sessler, D. Kim et al. einen neuen Anlauf. Wie durch das Akkordeon im Titelbild angedeutet, ergibt sich auch durch das Auseinanderziehen des Porphycen‐Gerüsts ein neuer...
A new expanded porphycene with 26 π‐electrons has been prepared by the McMurry coupling of 1,4‐bis(3,4‐diethyl‐2‐pyrryl)benzene dialdehyde. Expansion of the porphycene framework provides a ligand capable of stabilizing a bis(rhodium) and a monoruthenium complex. These new porphycene derivatives absorb strongly in the NIR spectral region, with appreciable absorptivity up to 1300 nm. On the basis of...
