title: Guest-induced irreversible sliding in a flexible 2D rectangular grid with selective sorption characteristics.
abstract: A 2D noninterpenetrated flexible metal-organic porous solid, {[Cu(2)(cis-chdc)(2)(bpee)] x H(2)O}(n) (1) based on a paddle-wheel building unit has been constructed using a mixed-ligand system. Guest-induced irreversible internetwork displacements of the 2D grids result in permanent porosity in the framework, as realized by the selective CO(2) sorption over N(2). The different affinity and selectivity of the solvent molecules was correlated with the internal polarity of the pore surfaces.
