Graphical Abstract

Rationally designed and synthesized, two novel pillar-layered 3D microporous frameworks {[Cd(pzdc)(azpy)]⋅2 H2O}n (1, left) and {[Cd(pzdc)(bpee)]⋅1.5 H2O}n (2, right) have high thermal stability and highly selective adsorption properties. Removal of guest water molecules results in the expansion of 1 but the contraction of 2.
