The Arene-Perfluoroarene Interaction

Use of the Arene-Perfluorarene Interaction in the Design of Solid State Structures 

One novel interaction that has been established as a way to design solids is the arene-perfluoroarene interaction. 

As an example of the use of a supramolecular synthon in materials design, we consider solid state diacetylene polymerization (see to the right). Single crystals of some diacetylene derivatives can be photopolymerized to produce long conjugated chains within the crystal. Because of their extensive conjugation, such polymerized diacetylenes have novel optical and electrical properties. For polymerization to occur, the diacetlyene must crystallize in a specific geometry that is conducive to polymerization—the potential reactive centers must be near each
