Abstract

Konformative SolvatochromieEin selbstorganisiertes chromophores Molekül zur Unterscheidung zwischen unpolaren Solventien stellen A. Tsuda, T. Aida et al. in ihrer Zuschrift auf S. 5231 ff. vor. Die Selbstorganisation eines Bis(zinkpyridylporphyrin)-Rotamers mit einer π-konjugierten Brücke liefert eine Mischung supramolekularer Kästen aus planaren und rechtwinkligen Konformeren mit unterschiedlichen Absorptionsspektren, deren Verhältnis sich je nach Solvens ändert und so zu einer solvatochromen Reaktion führt.
