Abstract: The use of porous crystalline solids constituted of a metal-organic framework (MOF) for the capture of polar volatile organic compounds (VOCs). In particular, the MOF of interest are material having an average pores sizes of 0.4 to 0.6 nm and an hydrophobic core formed by a metal oxide and/or hydroxide network connected by linkers, the linkers being selected from the group including (i) C6-C24 aromatic polycarboxylate linkers, such as benzyl or naphtyl di-, tri- or tetracarboxylate, and (ii) C6-C16 polycarboxylate aliphatic linkers; the linkers bearing or not apolar fluorinated groups, e.g. —(CF2)n—CF3 groups, n being a integer from 0 to 5, preferably 0 ou 3, and/or apolar C1-C20 preferably C1-C4 alkyl groups, e.g. —CH3 or —CH2—CH3, grafted directly to the linkers and pointing within the pores of the MOF.
