Abstract
A unique
step-by-step activation of the biporous material via formation of
the intermediate host–guest complex with a labile ligand has
been presented on the example of the metal–organic framework
[Zn<sub>4</sub>(ur)<sub>2</sub>(ndc)<sub>4</sub>]. The difference
in the chemical environment of channels allows highly selective separation
of the mixture of S<sub>4</sub>N<sub>4</sub> and benzene
