title: Structures, Magnetic Properties, and Aromaticity of Cyclacenes.
abstract: Two [2n]trannulene rings coupled through n C-C bonds dictate the properties and aromaticity of [n]cyclacenes (one possible valence isomer is shown schematically). Theoretical calculations indicate that [n]cyclacenes with even values of n constitute a novel class of organic semiconductors and magnetic materials.
