【摘要】 <正>利用羧酸配体与金属离子构筑新颖的超分子配合物的研究一直是配位化学领域的热点。作为超分子配合物构成要素之一的羧酸配体,其几何特征对超分子配合物的结构和性质具有重要的影响。已报道的超分子配合物中,出现最多的是刚性的高对称性羧酸配体,柔性羧酸也广泛的应用于超分更多还原

【Abstract】 Three novel complexes [Cu(dbsf)(H2O)]·(i-C3H8O)0.5 (1), [Cu(dbsf)(2,2’-bpy)(H2O)]·(i-C3H8O) (2) and [Cu(dbsf)(4,4’-bpy)0.5]·(H2O) (3) (H2dbsf = 4,4’-dicarboxybiphenyl sulfone, 2,2’-bpy = 2,2’-bipyridine, 4,4’-bpy = 4,4’-bipyridine and i-C3H8O = iso-propanol) have been synthesized under hydro/solvothermal conditions. Both complexes 1 and 2 are 3D supramolecular structures assembled by hydrogen bonds and π-π stacking interactions. But complex 1 is composed of 1D double-chain, while 2 consists of 1D Great-Wall-like chain. In complex 3, dbsⅡ-ligands and 4,4’-bpy ligands connect Cu(Ⅱ) ions to a catenane-like 2D network. These catenane-like 2D layers stack in ABAB fashion to form a 3D supramolecular structure.更多还原
