Phenyl–Perfluorophenyl Stacking Interactions: A New Strategy for Supermolecule Construction

Abstract

Photochemically induced polymerizations in the solid state of 1 · 2 and 3 depend on the intriguing interaction between phenyl and perfluorophenyl groups, which leads to an appropriate alignment of the molecules in the crystal. As with the 1:1 complex of benzene and hexafluorobenzene the diyne monomers are stacked alternately to form columns of arene groups.
