Highly Fluorinated Trianglimine Macrocycles: A Supramolecular Organic Framework

A novel highly fluorinated dialdehyde was prepared by a two-stage synthesis. This reactive building block for dynamic imine chemistry was used in a condensation reaction to generate the first extensively fluorinated trianglimine. An analysis of the material properties and, especially, the crystal structure of the [3+3] macrocycle revealed a supramolecular organic framework with tubular porous channels. The use of fluorinated ligands to generate hydrophobic electron-deficient channel-like pores is an important addition to the ever-expanding field of supramolecular networks and to trianglimine chemistry in general.

Superhydrophobic perfluorinated metal-organic frameworks

Three perfluorinated Cu-based metal-organic frameworks (MOFs) were prepared starting from extensively fluorinated biphenyl-based ligands accessed via C-H functionalization. These new materials are highly hydrophobic: with water contact angles of up to 151
