Efficient capture of trace benzene vapor by metal-organic frameworks modified with macrocyclic pyridyl ligands.

ABSTRACT: The capture of trace benzene vapor is an important and huge challenge due to its serious toxicity. Physisorbents usually exhibit weak interactions especially in the presence of trace concentrations, thus possessing poor removal performance. Herein, an efficient post-synthetic modification strategy with various mono-, bi-, and tri-pyridyl derivative ligands was performed on the parent [Fe₃(μ₃-O)(OH)(H₂O)₂(pet)] (NU-1500(Fe), H₆pet = peripherally extended triptycene, 4,4',4'',4''',4''',4'''-(9,10-dihydro-9,10-[1,2]benzenoanthracene-2,3,6,7,14,15-hexayl)hexabenzoic acid) with large hexagonal pores (14 × 19 Ų) and modifiable metal sites. Remarkably, these MOFs can regulate the performance of trace adsorption of benzene. Among t
