Halogen-bonded and interpenetrated networks through the self-assembly of diiodoperfluoroarene and tetrapyridyl tectons

The formation of two organic interpenetrated networks on halogen bonding driven self-assembly of diiodoperfluorarenes with tetrapyridyl tectons is described. Both architectures exhibit two-dimensional square 44 networks; with either a 2-fold interpenetration of class IIa or a 3-fold interpenetration of class Ia. Diiodoperfluoroarenes are proven robust tectons in the design of interpenetrated networks based on the expansion strategy.
