Metal-organic frameworks (MOFs) incorporating macrocycles for the selective capture and fixation of air toxins

Abstract

Reticular chemistry is a recently developed field that empowered scientists worldwide to creativelydesign new extended solid materials such as metal-organic frameworks (MOF) [1], with an exquisitecontrol over the topology and identity of the solid open spaces (i.e. pores at MOFs). This control onthe materials design led us to successfully prepare highly porous and crystalline materials forimpactful applications such as selective carbon dioxide capture [2a] and enzyme-inspiredheterogeneous catalysis [2b]. Recently, and supported by an ONRG NICOP grant, we targeted thedesign and preparation of emissive MOFs capable of detecting and selectively capturing organicmodel compounds for chemical warfare agents (CWAs). The obtained results on this project inspiredus to covalently incorporate macrocycles to the MOFs structure. We believe that their rich andselective host-guest chemistry [3] can be expanded to porous solids to develop a new generation ofefficient adsorbents for air toxins. This strategy has only recently been explored in literature [4], andhas an enormous potential for the MOFs field and porous materials in general. We anticipate thatsuccessfully incorporation of this rich supramolecular chemistry to the pores of MOFs will lead to anew generation of highly selective and efficient adsorbent materials for capturing air toxins
