Formation and characterization of crystalline molecular arrays of gas molecules in a 1-dimensional ultramicropore of a porous copper coordination polymer

A strategy for observing regular assemblies of guest molecules to utilize the well-regulated one-dimensional (1D) channel of porous coordination polymers is presented. Obtaining crystal structures indicate that guest molecules are confined in a linear fashion to form crystalline-like regular ordered arrays, which are characteristic of the kind of gas molecules and the geometrical and potential properties of the ultramicropore.
