Giant Polycyclic Aromatic Hydrocarbons and the Metals That Bind Them

Abstract

Starting from 1 (J. Am. Chem. Soc. 2004, 126, 7794) the authors elaborate to a wide variety of compounds. All of the compounds described were readily soluble in organic solvents due to the disruption of the planarity of the aromatic system by the bulky tert-butyl groups, as described in J. Am. Chem. Soc. 2006, 126, 1334. Of particular note were compounds 2-4: Nano­graphene 2 possessed a well-resolved 1H NMR spectrum, the largest polycyclic aromatic hydrocarbon (PAH) to do so. Complex 3 represents the largest ligand ever complexed to a metal center. Finally 4 is the largest known phthalocyanine derivative.
