lic acid, H2OBA = 4,4′-oxydibenzoic acid, H3NTB = 4,4′,4′′-nitrilotribenzoic acid, DMF = N,N-dimethylformamide), were successfully fabricated and structurally characterized. Due to the variety of organic linkers, 1–3 exhibit varied topologies: 1 is a 4-c three-dimensional (3D) framework with 65·8} topology, 2 is a 6-c 3D net with point symbol of 44·610·8}, and 3 is a 4-c two-dimensional network that
三种新型荧光Zn( II )骨架,即[Zn(DPA)(NDA)] 2 ·2DMF ( 1 )、[Zn 2 (DPA)(OBA) 2 ]·2DMF·4H 2 O ( 2 )和[Zn( DPA)(HNTB)]·H 2 O ( 3 ) (DPA = 2,5-二(吡啶-4-基)苯胺, H 2 NDA = 1,4-萘二甲酸, H 2 OBA = 4,4'-羟基二苯甲酸, H 3 NTB = 4,4',4''-次氮基三苯甲酸, DMF = N , N-二甲基甲酰胺), 成功地制造和结构表征。由于有机接头的多样性,1-3表现出不同的拓扑:1是具有6 5 ·8}拓扑的4-c三维(3D)框架, 2是点符号为4 4 ·6 10 ·8}的6-c 3D网络,3是4- c 二维网络通过与4 4 ·6 2 }拓扑结构的氢键相互作用进一步堆叠成3D结构。荧光相关实验表明,1-3可用于快速识别CrO 4 2- /Cr
