Dynamic covalent gels are synthesized from an aromatic trialdehyde and α,ω-dinitroalkanes via the nitroaldol reaction in organic solvents. The gelation process can be fine-tuned by changing the starting nitroalkanes, solvents, feed concentration, catalyst loading, or reaction temperature. The resulting organogels demonstrate good structural integrity and excellent self-healing ability. Intact xerogels are produced upon drying, without damaging the network, and the solvent-free network can recover its gel form in the presence of an organic solvent. Furthermore, the crosslinked dynameric gel depolymerize to small molecules in response to excess nitromethane.
