Through solvothermal reaction of In(NO3)3·5H2O 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.

Because of the discovery of a high-symmetry rare-earth hexanuclear secondary building unit, controllable design and assembly of rare-earth organic frameworks (REOFs) have become feasible. Subsequently, series of isoreticular/structural fcu REOFs platform was herein successfully produced by solvothermal reactions and reticular chemistry. After the crystal structural information and permanent porosity were confirmed, thorough investigations toward photoluminescence and hydrothermal stability were implemented. As a result, distinct and interesting luminescence behavior is observed among the series of REOFs. 1-Dy and 2-Dy mainly display ligand-centered emission, while 1-Eu and 2-Eu are predominated by metal-centered emission. More interestingly, 1-Eu reveals excitation dependent luminescence, generating the first example of a white light emission phosphor in single phase fabricated from a sole Eu3+ ion and sole organic linker. 2-Eu however does not exhibit such features and stays mostly unchanged upon the variation of excitation light. The above luminescence features were correlated by determination of the triplet state T1 energy of both L1 and L2 linkers via the phosphorescence at 77 K of 1-Gd and 2-Gd. Lastly, water resistance of the series of fcu REOFs was valued and it was found that 1-Dy constructed from a smaller ion radius and shorter organic linker exhibits the most prominent hydrothermal stability among the series of REOF platforms.

A 2-periodic copper–organic framework of 1 has been deliberately obtained via solvothermal reaction between Cu(NO3)2·3H2O and a V-shaped highly conjugated organic linker. Single-crystal X-ray structural analyses reveal that 1 displays a 3D stacking structure along with channel-typed interior architectures decorated with amino and trifluoromethoxy functionalized groups. 1 demonstrates not only notably selective encapsulation of small-sized MB and MO molecules with high adsorption rate, but also efficient photodegradation activities through decomposing MB, MO and large-sized phthalocyanine of reactive blue 21 under visible light irradiation.Solvothermal reaction between Cu(NO3)2·3H2O and a V-shaped highly conjugated organic linker, a 2-periodic copper–organic framework of 1 has been deliberately obtained.
