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.

Pressure-related sensing materials in mechanochromic luminescent materials have received wide attention.However,at present,most piezochromic luminescence (PCL) materials have problems such as aggregation-caused quenching (ACQ) effect due to the presence o
The widespread applications of aggregation-induced emission luminogens (AIEgens) inspire the creation of AIEgens with novel structures and functionalities.In this work,we focused on the direct and effi-cient synthesis of a new type of AIEgens,imidazo[1,5-
