Covalent organic-frameworks (COFs) are an emerging class of porous and ordered materials formed by condensation reactions of organic molecules. Recently, the Schiff-base chemistry or dynamic imine-chemistry has been widely explored for the synthesis of COFs. The main reason for this new tendency is based on their high chemical stability, porosity and crystallinity in comparison to previously reported COFs. This critical review article summarizes the current state-of-the-art on the design principles and synthetic strategies toward COFs based on Schiff-base chemistry, collects and rationalizes their physicochemical properties, as well as aims to provide perspectives of potential applications which are at the forefront of research in materials science.

Herein, a novel magnetic resorcinol-formaldehyde-supported isatin-Schiff-base/Fe complex (FeO@RF-ISB/Fe) is prepared and characterized and its catalytic performance is investigated in the synthesis of pyrano[2,3-]pyrimidines. The FeO@RF-ISB nanomaterial was prepared through the chemical immobilization of (3-aminopropyl)trimethoxysilane over the FeO@RF composite, followed by treatment with isatin. The FeO@RF-ISB was then reacted with FeCl·6HO to afford the FeO@RF-ISB/Fe nanocatalyst.

A new series of quinoline Schiff-bases was designed, synthesized, and characterized using 1H NMR, 13C NMR, and HRMS analysis. Further, all the compounds were screened for their antitubercular, antibacterial, and antifungal activity, and the minimum inhibitory concentrations (MICs) were determined. Among all, compound 7f displayed a significantly potent broad-spectrum antitubercular and antimicrobial activity against most of the tested strains of bacteria and fungi, with MIC values in the range of 1.

In the present study, biopolymeric Schiff base (SB) ligands were synthesized from chitosan and isatin. Consequently, their earth abundant transition metal complexes of cobalt and copper were synthesized. All compounds were extensively characterized using FTIR and UV spectroscopy, thermo-gravimetric (TG) analysis, X-ray powder diffraction (XRD) and FESEM (field emission scanning electron microscopy).

The root ducts play an important role in the plant's transport of nutrients from the soil. Based on the selective transport characteristics of plant roots, amino pillar[6]arene bionic porous root sub-nano channel membrane were constructed to remove Imazamox. Imazamox (IM) is an effective imidazolinone herbicide frequently utilized in soybean fields to control a wide range of annual grasses and broad-leaved weeds.
