Abstract:We designed a trigonal symmetric imine-linked covalent organic framework (COF), TFPC-DAB, with control over the angularity of the building units, where a bent C2-symmetric diamine, such as 1,3-diaminobenzene (1,3-DAB or DAB), with an exo-angle of 120° was used instead of those with an exo-angle of 180°, in combination with a C3-symmetric trialdehyde, such as tri(4-formylphenoxy)cyanurate (TFPC). Its synthesis was accomplished by reacting the building units in a mixture of mesitylene/dioxane/6 M acetic acid und… Show more
Structurally tunable covalent organic frameworks (COFs) have emerged as promising electrocatalysts for the oxygen reduction reaction (ORR) due to their highly controllable functionality and porous channels. We have constructed imine-linked...
