A carbazole-embedded cyclodimer adopting a helical conformation and metal-ion sensing
An unprecedented formation of carbazole-embedded decaphyrin through acid-catalyzed condensation of appropriate coupling partners is reported. Single crystal X-ray diffraction analysis revealed that the macrocycle adopted a 'figure-of-eight<i>'</i> structure, wherein two pyrrole and thiophene rings were inverted. The absorption spectrum of the macrocycle exhibited ill-defined bands and it shows specific affinity towards soft metal ions such as Ag<sup>+</sup> and Hg<sup>2+</sup>.
