Simplified schematics of the original ionic cross-linking configurations (a) H-link and (b) T-link. Combinations of fundamental linking types lead to (c) secondary linking types. In configuration (c), the dotted monomer structures are off-plane and form T-links with the TPP units below them. Reproduced from [50].
