Two series of isoreticular chiral metal-organic frameworks assembled from Ln(III) (Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb), Na(I), and chiral flexible-achiral rigid dicarboxylate ligands, formulated as [NaLn(Tart)(BDC)(H(2)O)(2)] (S1) and [NaLn(Tart)(biBDC)(H(2)O)(2)] (S2) (H(2)Tart = tartaric acid; H(2)BDC = terephthalic acid; H(2)biBDC = biphenyl-4,4'-dicarboxylic acid), were obtained as single phases under hydrothermal conditions. The compounds have been studied by single-crystal and powder X-ray diffraction, thermal analyses (TG-MS and DSC), vibrational spectroscopy (FTIR), scanning electron microscopy (SEM-EDX), elemental analysis, and X-ray thermodiffractometry. The catalytic activity has been also investigated. The photoluminescence properties of selected compounds have been investigated, exhibiting room temperature tunable UV-vis-IR light emission.
两个系列的等孔手性金属有机骨架由 Ln(III)（Ln = Sm、Eu、Gd、Tb、Dy、Ho、Er、Yb）、Na(I)和手性柔性-非手性刚性二羧酸配体组装而成，分别表示为[NaLn(Tart)(BDC)(H(2)O)(2)]（S1）和[NaLn(Tart)(biBDC)(H(2)O)(2)]（S2）（H(2)Tart = 酒石酸；H(2)BDC = 对苯二甲酸；H(2)biBDC = 联苯-4,4'-二羧酸），在水热条件下作为单相物获得。通过单晶和粉末 X 射线衍射、热分析（TG-MS 和 DSC）、振动光谱（FTIR）、扫描电子显微镜（SEM-EDX）、元素分析和 X 射线热分析研究了这些化合物。还研究了它们的催化活性。研究了选定化合物的荧光性质，表现出室温可调谐的紫外可见红外光发射。
