【Abstract】 Recently,construction of crystalline bioinspired frameworks incorporating functionality as well as flexible porosity has attracted growing interests.The dipeptide molecules as flexible linkers have received considerable attentions because of their structural diversity and biocompatibility.In this communication,we present two supramolecular complexes [Cu₄（C₅H₈N₂O₃）₄（H₂O）₄(C₁₀H₈N₂)₂]·(C₁₀H₈N₂)·8H₂O（1）and[Cu₄(C₈H₁₄N₂O₃)₄ （H₂O）₂(C₁₀H₈N₂)₂]·(C₁₀H₈N₂)·13H₂O（2）,obtained through utilizing glycyl-L-alanine（for 1） and glycyl-L-leucine（for 2） as linkers and 4,4’-bipyridine as bridging ligands.Resulting ternary Cu（Ⅱ）-dipeptide comlexes show the ability to host 4,4’-bipyridine molecules,which result in intriguing porous structures through different host-guest interactions.Moreover,slight difference in side chains of dipeptides results in completely different host-guest interactions.Guest 4,4’-bipyridine exerts an influence on hydrogen-bonding interactions of host complexes through different host-guest interactions which is crucial to form porous frameworks of 1 and 2.更多还原
