Self-assembly of aromatic sulfonamide-amide hybridized molecules: formation of 2D layers and 3D microporous networks in the solid state

Three sulfonamide-amide hybridized molecules and one cyclic analogue were synthesized and their assembling behaviors in the solid state were investigated by X-ray crystallography. The results showed that the hybridized molecules could be not only induced to take up helical secondary structures by a network of intramolecular hydrogen bonds, but also utilized as useful building blocks for assembling into 1D zigzag chains and superhelices, 2D layers and further 3D networks. Moreover, it was found that the multiple C-H?OS hydrogen bonds played an important role in the assembling processes.
