Exploration of stable, crystalline, porous covalent organic frameworks

Hong Xu, a Ph.D. at the Institute for Molecular Science, National Institutes of National Sciences, and his colleagues challenged for the design and synthesis of stable, crystalline, porous, covalent organic frameworks. By incorporating electron-donating groups to the phenyl rings of imine linkages, they found that the polarization of imine bonds were softened; this electronic effect reduces the repulsion between layers and strengthens the interlayer interactions to reinforce the stability of the resulting COFs. —> Read More
