2,4-二羟基-1,5-苯二磺酸、邻二氮菲通过水热法自组装合成了一个新颖的超分子化合物(H_2L)^(2-)·2(phen)^+·2(H_2O),其中配体L=2,4-二羟基-1,5苯二磺酸。并对其进行了元素分析、红外光谱分析、荧光光谱分析、热稳定性分析、单晶及粉末X射线衍射等相关表征。结构分析表明,晶体属于单斜晶系,I 2/c空间群。所合成化合物的晶体学不对称单元由一个质子化的邻二氮菲阳离子、半个处于C_2轴位置的2,4-二羟基-1,5-苯二磺酸阴离子以及一个游离水分子组成。此外超分子化合物在室温下还表现出较强的蓝色荧光发射。

Self-assembly of 2, 4-dihydroxy-1, 5-benzenedisulfonic acid and o-phenanthroline by hydrothermal method to synthesize a novel supramolecular compound （H2L）^2-·2（phen）^＋·2（H2O）（ L = 2, 4-dihydroxy-1, 5-benzenedisulfonic acid）, and they are characterized by elemental analysis, IR, PL, TG, single crystal and powder X-ray diffraction. Structure analyses indicate that the crystal belongs to monoclinic system, I2/c space group. The crystalline asymmetric unit of the compound consists of a protonated o-phenanthrene cation, a half sulfonic acid anion at the C2 axis position, and a free water molecule. In addition, the supramolecular compound exhibits strong blue fluorescence emission in solid state at room temperature.
