Abstract
The separation of xylene isomers is one of the most challenging tasks in the petrochemical industry. Herein, we developed an efficient
adsorptive molecular sieving strategy using crystalline trianglimine macrocycle (1) to separate the elusive m-xylene isomer from an
equimolar xylenes mixture with over 91% purity. The selectivity is attributed to the capture of the preferred guest with size/shape
selectivity and C–Hp interactions. Moreover, the trianglimine crystals are readily recyclable due to the reversible transformation between
the guest-free and guest-loaded structures.
