A novel hydrogen-bonded organic frameworks (HOFs) FJU-200 has been constructed from N,N'-bis(5-isophthalic acid)naphthalimide (H4L). FJU-200 has a good dual-function of aniline and ultraviolet detection. FJU-200 is the first case of HOF with dual sensing of visual color changes and photoluminescence quenching for aniline detection, and the detection limit of aniline can reach 5.5 × 10?4 mol/L. Under ultraviolet FJU-200 will rapidly change from light yellow to rustic brown, which makes it possible to use FJU-200 to achieve minute-level ultraviolet detection. Moreover, for more convenient use, FJU-200 test papers are prepared. Using them, convenient and fast aniline or ultraviolet detection can be realized. The single-crystal X-ray structures show that compared with the original FJU-200, both PhNH2@FJU-200 and UV-FJU-200 have larger pore sizes, and the dihedral angles of the H2L2? in framework has been changed.

Nitroaromatics are some of the most hazardous compounds that contaminate water and are also used in explosives. The selective detection of nitroaromatics is highly warranted but at the same time very challenging. This is due to the similarities in their size, shape and functionality. However, if a system is cleverly designed to enforce selective host-guest interactions, the detection of one particular class of nitro compounds can be successfully achieved. Metal-organic frameworks (MOFs) have emerged as promising porous materials for these applications. Herein, a fluorescent Zr-NDI based MOF has been reported for the selective detection of trinitrophenol (TNP) in water. Interestingly, the high fluorescence behaviour of the MOF can be quenched only by nitrophenol derivatives, particularly TNP, whereas the other classes of nitroaromatic and nitroaliphatic compounds have no impact on the fluorescence properties of the MOF. The limit of detection of TNP is as low as 8.1 ppm and the quenching efficiency is 95%. DFT studies have been carried out in conjunction with experiments that reveal favourable host-guest interactions for the selective binding of the hydroxyl group present in TNP.

The Schottky barrier created at the interface between electron sinks and semiconductors can effectively optimize electron transfer for active photocatalysis. However, heterogeneous photocatalytic organic transformations via the Mott Schottky effect are st
