Crystal engineering of a rectangular sql coordination network to enable xylenes selectivity over ethylbenzene.

ABSTRACT: Separation of the C8 aromatic isomers, p-xylene (PX), m-xylene (MX), o-xylene (OX) and ethylbenzene (EB), is relevant thanks to their widespread application as chemical feedstocks but challenging because of their similar boiling points and close molecular dimensions. Physisorptive separation could offer an energy-efficient solution to this challenge but sorbents which exhibit strong selectivity for one of the isomers remain a largely unmet challenge despite recent reports of OX or PX selective sorbents with high uptake capacity. For example, the square lattice, sql, topology coordination network [Co(bipy)₂(NCS)₂] _n (sql-1-Co-NCS) exhibits the rare combination of high OX selectivity and high uptake capacity. Herein w
