Columnar Superstructures of Non-Disc-Shaped Molecules Generated by Arene-Perfluoroarene Face-to-Face Interactions

摘要

Arene-perfluoroarene interaction is known as a strong face-to-face interaction between perfluorinated and nonfluori-nated aromatic rings.It has been reported that the interaction was not a donor-acceptor interaction,that it originated in both dispersion and electrostatic interactions,and that the dispersion interaction was more effective than the electrostatic interaction.The sum of the dispersion and electrostatic energies between benzene and hexafluoroben-zene molecules was estimated to be 3.7-5.6 kcal mol~(-1).
