Bond breaking is an essential process in chemical transformations and the ability of researchers to strategically dictate which bonds in a given system will be broken translates to greater synthetic control. Here, we report extending the concept of selective bond breaking to reticular materials in a new synthetic approach that we call Clip-off Chemistry. We show that bond-breaking in these structures can be controlled at the molecular level; is periodic, quantitative, and selective; is effective in reactions performed in either solid or liquid phases; and can occur in a single-crystal-to-single-crystal fashion involving the entire bulk precursor sample. We validate Clip-off Chemistry by synthesizing two topologically distinct 3D metal-organic frameworks (MOFs) from two reported 3D MOFs, and a metal-organic macrocycle from metal-organic polyhedra (MOP). Clip-off Chemistry opens the door to the programmed disassembly of reticular materials and thus to the design and synthesis of new molecules and materials.

The high yield synthesis of an isophthalic acid derivative bearing a nitronyl-nitroxide moiety at the 5-position was achieved. The structural analysis in the crystalline phase by X-ray diffraction on single crystals revealed the formation of a 3-D network through strong H-bonds between the acid groups and the nitronyl-nitroxide moieties. The spin label obtained was also analysed by EPR spectroscopy which showed a five line pattern with a(N)=7.51 G and a g-factor of 2.0066. Magnetic measurements revealed that at low temperature, the systeme showed a Curie-Weiss like behaviour with weak ferromagnetic intermolecular interactions.
