Direct attachment of two 2-ureido-4-[1H]-pyrimidinone (UPy) subunits to a 3,6-carbazolyl core gives rise to a highly viscous, supramolecular polymer. However, insertion of a methylene spacer between the UPy’s and the carbazole leads to a well-defined, cyclic tetramer, in a belt-shaped arrangement, as evidenced by MALDI-TOF, DOSY, and NOESY spectra.
A new type of –NH– bridged azacalix[2]arene[2]carbazoles has been synthesized by aromatic nucleophilic substitution reaction via one pot and/or fragment coupling strategy. Both symmetric and unsymmetric macrocycles are obtained. X-ray single crystal analysis reveals 1,3-alternation conformation of the macrocycle. The spectroscopic and electrochemical properties of the macrocycles are also explored
