An Efficient, One-Step Synthesis of 2,4,6-Triaminobenzene-1,3,5-tricarboxylaldehyde

This report details the synthesis, isolation, and characterization of a hexa-functional monomer, 2,4,6-triaminobenzene-1,3,5-tricarboxylaldehyde, which consists of a single benzene ring with three pendant aldehyde groups alternating with three free amine groups. This compact, symmetrical monomer may be especially useful to produce dense, triangular-lattice, imine-based 2D polymers such as graphimine, or as a starting material for other high-value, nitrogen-rich chemicals such as pharmaceuticals and energetic compounds.
