Covalent organic frameworks (COFs) have attracted considerable interest over the past few years, but the available type of monomers is still limited. Herein, two novel imine-linked COFs (TaDAP and TaDA) were constructed by the condensation of 1,3,5-tris-(4-aminophenyl) triazine with 2,6-diformylpyridine (forming TaDAP) and 1,3-benzenedialdehyde (forming TaDA) under solvothermal conditions. The structures of the COFs were confirmed and characterized by solid state 13C NMR, FT-IR, PXRD, TGA, SEM, TEM and nitrogen sorption isotherms. They appear as regular spherical particles and possess excellent thermal stability. It was also found that their dispersions emit strong fluorescence, and display quick response to certain metal ions. In particular, TaDAP can detect Fe3+ with sensitivity and selectivity. Moreover, both the COFs present excellent catalytic activity towards the Knoevenagel reaction. Accordingly, this study not only provides a new way to enrich the family of COFs, but also develops their potential applications in metal ion detection. In the part of experimental materials, we found many familiar compounds, such as 2,6-Pyridinedimethanol(cas: 1195-59-1Electric Literature of C7H9NO2)
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Electric Literature of C7H9NO2
