A Saddle‐Shaped Expanded Porphyrinoid Fitting C60**

Abstract

AbstractWe present the synthesis of a new type of an expanded porphyrinoid macrocycle with a saddle‐shaped morphology and its complexation of C60 guest molecules. The new macrocycle contains four carbazole and four triazole moieties and can be readily synthesized via a copper‐catalyzed click reaction. It shows specific photo‐physical properties including fluorescence with a high quantum yield of 60 %. The combination of the saddle‐shaped geometry with the expanded π‐system allows for host–guest interactions with C60 in a stacked polymer fashion. Evidence for the presence of a host–guest complex is provided both in solution by NMR spectroscopy and in the solid state by X‐ray structure analysis.
