通过In（NO3）（3）中心点5 H（2）O与一种高度共轭的羧酸酯基三配位连接剂的溶剂热反应，成功地制备了一种双互穿的铟-有机骨架化合物1。单晶X-射线衍射结果表明，化合物1具有阴离子骨架和通道型内部空间，内部充满咪唑环和羧酸根氧。由于其独特的结构特征，1不仅表现出对阳离子MB和阴离子MO分子的选择性吸附，具有高选择性、吸收率和吸附率，以及良好的可逆性和可回收性，而且还表现出在紫外光照射下高效分解染料MB和MO的光催化活性。由于形成MB@1和MO/1复合物，可见光或紫外光。MB@1和MO/1可见光响应复合材料的新发现可能会开辟更多的应用领域。
Through solvothermal reaction of In(NO3)(3)center dot 5H(2)O and a highly conjugated carboxylate-based tritopic linker, a doubly interpenetrated indium-organic framework, 1, has been successfully prepared. As revealed by single-crystal X-ray diffraction, the isolated 1 displays an anionic framework and channel-type interior spaces replete with imidazole rings and free carboxylate oxygens. Due to its unique structural features, 1 demonstrates not only selective adsorption of cationic MB concomitant with anionic MO molecules with high selectivity, uptake, and adsorption rate, and good reversibility and recyclability, but also photocatalytic activity to efficiently decompose dyes MB and MO under the illumination of either UV or visible light due to the formation of MB@1 and MO/1 composites. The new finding of visible light responsive MB@1 and MO/1 composites may open up more applications.
