摘要：

A Cu complex-assembled compound [Cu(bpy)(BF4)(2)(H2O)(2) . (bpy)](n) (bpy = 4,4'-bipyridine) with non-interpenetrated structure was synthesized and its adsorption properties for N-2, Ar, and CO2 were studied. The adsorption of gas on this complex suddenly begins at a definite relative pressure ('gate pressure') regardless of almost nil adsorption below the gate pressure. Such a unique adsorption phenomenon is attributed to the hydrogen bond-regulated microporous nature of this complex; hydrogen bonds in pores block adsorption below the gate pressure. Additionally, the gate pressure depends on both the adsorbate and the pretreatment temperature of the Cu complex solid. (C) 2001 Elsevier Science B.V. All rights reserved.
