摘要
以 4,8-二磺-2,6-萘二甲酸（H4dsndc）为基础，获得了五种新的金属有机框架：[Cd2(dsndc)(dmf)6]（1）、[Mn2(dsndc)(dmf)6]（2）、[Zn2(dsndc)(dmf)6]（3）、[Co2(dsndc)(dmf)6]（4）和[Cd2(dsndc)(dma)6]（5）（DMF = N,N-二甲基甲酰胺，DMA = N,N-二甲基乙酰胺）。其中四种化合物（1-4）是等结构层状配位聚合物。所有化合物的结构都是通过单晶 X 射线衍射分析确定的。化合物 1-3 和 5 是化学纯和相纯的，并通过标准的复合物理化学技术（粉末 X 射线衍射、红外光谱、热重分析和 CHN）进行表征。记录了化合物 3 的光致发光激发光谱和发射光谱，量子产率为 18%。
A Series of Coordination Polymers Based on 4,8-Disulfo-2,6-Naphthalenedicarboxylic Acid
Five new metal-organic frameworks based on 4,8-disulfo-2,6-naphthalenedicarboxylic acid (H4dsndc) are obtained: [Cd2(dsndc)(dmf)6] (1), [Mn2(dsndc)(dmf)6] (2), [Zn2(dsndc)(dmf)6] (3), [Co2(dsndc)(dmf)6] (4), and [Cd2(dsndc)(dma)6] (5) (DMF = N,N-dimethylformamide, DMA = N,N-dimethylacetamide). The four of them (1–4) are isostructural layered coordination polymers. The structures of all compounds are determined by the single crystal X-ray diffraction analysis. Compounds 1–3 and 5 are obtained as chemically and phase-pure and are characterized by the standard complex of physicochemical techniques (powder XRD, IR, TGA, and CHN). Photoluminescence excitation and emission spectra are recorded for compound 3, and a quantum yield of 18% is obtained.
