Carbo-aromaticity” and novel carbo-aromatic compounds

Recent advances in experimental and theoretical studies of carbo-benzene derivatives, along with the proposition of a generalization of the definition of aromaticity to the two-membered π-rings of triple bonds, suggest relevance for the notion of “carbo-aromaticity”.

Cyclophanes containing large polycyclic aromatic hydrocarbons

Big, bigger, biggest. This Review puts the spotlight on the handful of PAHs with four or more rings that have been incorporated into cyclophanes. Lessons in synthesis, structure, fundamental concepts and properties abound in these remarkable molecules that feature PAHs ranging in size from pyrene to hexabenzocoronene.
