During the past century, synthetic macrocyclic molecules gained ever-growing interest among the chemists all around the world. Significant portion of this interest has been directed toward the macrocyclic arenes due to the several interesting features including the symmetrical structure, preformed cavities, host-guest interactions, etc. Despite the vast applications of these molecules, majority of them can be classified in a few classes based on the repeating unit and connectivity pattern. For example, calixarenes and pillarenes are meta and para methylene-bridged substituted benzene molecules, respectively. Herein, we present a new family of contorted tubular arenes that we have termed tubularens – tubular-shaped radially-conjugated nanotubes – which provide a wide range of novel properties and readily synthesis that rival stat-of-the-art methodologies reported for strained polyaromatics. Tubularene’s length, solubility, cavity size, and electronic properties are highly tunable and modular. One remarkable aspect of these species is their rigidity, which we envision as a size-selective host for future applicatons.
