Our current work is focused on the synthesis and characterization of new aromatic systems characterized by extended pi-conjugation. We are interested in designing non-planar aromatic systems exhibiting various types of distortion, e.g. bowl-shaped, tubular, Möbius-strip, etc. The key properties under investigation are aromaticity, conformation, tautomeric equilibria, supramolecular interactions, and mesophase self-assembly.
