Abstract

Persistent carbocations derived from polycyclic aromatic hydrocarbons in superacid solutions were analyzed by NMR measurements. Their signals were assigned by 2D NMR techniques and positive charge delocalizations were estimated on the base of relative 13C chemical shift values to those of parent hydrocarbons. Electronic structures were also studied by the DFT method.
