Interaction of positively and negatively charged aromatic hydrocarbons with benzene and triphenylene: Towards a model of pure organic insulators

Abstract

[eng] A theoretical study of the complexes formed by two aromatic charged hydrocarbons, cyclopropenyl cation and phenalenyl anion, with benzene and triphenylene has been carried out. The binary complexes between the charged molecules and the neutral ones have been characterized as well as the ternary systems with the neutral systems acting as insulators of the charged ones. In the ternary complex a cooperative effect is observed both in the energy and in the geometry. In general, the interaction with ions reduces the aromaticity of the insulators.
