Robust Nanoporous Supramolecular Network Through Charge-Transfer Interaction

A robust nanoporous supramolecular network stabilized by charge-transfer interactions has been successfully constructed based on bipyridinium and bicarboxylic acid with electron-donating hydroxyl pendant groups, which exhibit high durability toward extensive acid/base condition (pH: 2-12), organic solvents, and the plucking of metal ions. Furthermore, the separation capacity toward rhodamine B and other dyes with the same charge and smaller molecular sizes has been realized in it.
