Syntheses, structural characterizations, photoluminescence, and adsorption properties of three new azo-functionalized Cd(II)-MOFs, namely, {[Cd(azbpy)(msuc)]·2.5(H2O)}n (2), {[Cd(azbpy)(mglu)]·5(H2O)}n (3), and {[Cd1.5(azbpy)2(glu)]·(NO3)·MeOH}n (4) [where msuc2− = methylsuccinate; mglut2− = methylglutarate; glut2− = glutarate; azbpy = 4,4′-azobispyridine] have been reported. The compounds show different structures only with the variation of aliphatic dicarboxylates. The photoswitching behavior for the above-mentioned newly synthesized Cd(II)-MOFs along with one of our previously reported other azo-functionalized Cd(II)-MOF, namely, {[Cd(azbpy)(suc)]·2(H2O)}n (1), has been studied extensively. At photoilluminated condition, the conductivity values can draw a clear structure–property relationship among the structures of compounds 1–4. Single crystal structural analysis reveals that all the compounds exhibit a three-dimensional (3D) framework connected by azbpy linker and respective aliphatic dicarboxylate through their bis-chelating mono/bis oxo-bridging fashion. Compounds 1–3 exhibit an iso-structural honeycomb like 3D framework showing the same coordination environments, where the metal-carboxylate 2D sheets of compounds 1–3 are pillared by N,N′-donor azbpy linkers. On the other hand, compound 4 exhibits a 2-fold interpenetrated 3D framework with a little difference in its coordination environment and the pillaring of 1D metal-carboxylate ladder by azbpy linkers. All the compounds significantly demonstrate their enhanced sensitivity under light rather than the dark condition. The gas and solvent vapor sorption studies have been performed for the synthesized compounds 2–4. Moreover, compound 2 exhibits an enhanced type IV selective CO2 adsorption isotherm over N2 along with the appearance of gate opening phenomena in that.

一组显示光开关特性和选择性CO 2吸附的多功能偶氮功能化半导体Cd（II）-MOFs
三种新型偶氮官能化的Cd（II）-MOF的合成，结构表征，光致发光和吸附性能，即{[Cd（azbpy）（msuc）]·2.5（H 2 O）} n（2），{[ Cd（azbpy）（mglu）]·5（H 2 O）} n（3）和{[Cd 1.5（azbpy）2（glu）]·（NO 3）·MeOH} n（4）[其中msuc 2 - =琥珀酸甲酯; mglut 2- =戊二酸甲酯；过剩2−=谷氨酸; 已经报道了azbpy ＝ 4，4′-偶氮二吡啶]。该化合物仅在脂肪族二羧酸盐变化的情况下显示出不同的结构。上述新合成的Cd（II）-MOF与我们先前报道的其他偶氮官能化Cd（II）-MOF之一即{[Cd（azbpy）（suc）]·2（H 2 O）} n（1）已被广泛研究。在photoilluminated条件下，导电率值可以得出的化合物的结构中一个明确的结构-性能关系1 - 4。单晶结构分析表明，所有化合物均表现出通过azbpy接头与各自的脂族二羧酸酯通过其双螯合单/双氧代桥联方式连接的三维（3D）骨架。化合物1 - 3表现出异结构蜂窝状等三维框架显示相同的配位环境，其中化合物的金属羧酸盐的2D片材1 - 3由N，N'-施主azbpy接头柱。另一方面，化合物4展示了2倍互穿的3D框架，其配偶环境和由azbpy接头在1D金属-羧酸盐梯子的柱基上几乎没有差异。所有化合物在光而不是黑暗条件下均显示出增强的敏感性。气体和溶剂蒸气吸附研究已用于将合成的化合物进行2 - 4。此外，化合物2表现出增强型IV选择性CO 2吸附等温线在N 2与闸门开现象，所述外观沿。
