The synthesis of unprecedented fused azacalixarenes (dimers and trimer) through successive nucleophilic aromatic substitutions is described. Absorption spectrophotometric and theoretical studies demonstrated that these oligomers share common phenyl moieties that enable conjugation of the whole π-system and a multiconcave geometry with aligned cavities because of the high flexibility of these macrocycles
