合成了2,9-二甲基-1,10-邻菲罗啉的铀(Ⅵ)超分子杂化配合物[UO2Cl4]2[dmphenH2]2·3H2O(1),并进行了IR、UV、XPS和X单晶衍射分析。铀的杂化配合物呈六配位的变形八面体结构,属单斜晶系,Cc空间群;晶胞参数分别为:a=1.7043(2)nm,b=0.8809(13)nm,c=2.7492(10)nm,α=90°,β=94.493(2)°,γ=90°,Z=4,V=4.1149(8)nm3。氢键和π…π相互作用大大加强了配合物的稳定性。配位导致紫外光谱的最大吸收峰发生红移。荧光光谱显示,配合物在407 nm的光激发下可发射506.6 nm绿色荧光。电化学研究表明,该配合物具有一对可逆的氧化还原峰和一个不可逆的还原峰。该配合物在紫外光照射下显示出极高的光催化活性。CCDC:780721
(UO2Cl4] 2 [dmphenH2] 2 · 3H2O (1) with 2,9-dimethyl-1,10-phenanthroline was synthesized and characterized by IR, UV, XPS and X single crystal diffraction analysis. The complex of uranium has hexacoordinated deformed octahedral structure and belongs to the monoclinic and Cc space group. The unit cell parameters are a = 1.7043 (2) nm, b = 0.8809 (13) nm, c = 2.7492 (10) nm, α = 90 °, β = 94.493 (2) °, γ = 90 °, Z = 4, V = 4.1149 (8) nm3. Hydrogen bonding and π ... π interaction greatly enhance the stability of the complex. The coordination results in a red shift of the maximum absorption peak of the ultraviolet spectrum. Fluorescence spectra showed that the complex emitted 506.6 nm green fluorescence at 407 nm. Electrochemical studies show that the complex has a pair of reversible redox peaks and an irreversible reduction peak. The complex shows very high photocatalytic activity under UV irradiation.
