Five water-soluble flexible organic frameworks have been synthesized from a pyridinium-derived tetracationic tetraaldehyde and five diacylhydrazines (1 : 2) through the quant. formation of a hydrazone bond in water at ambient temperature Dynamic light scattering experiments reveal that the homogeneous frameworks display hydrodynamic diameters ranging from 68 nm to 167 nm, which can be tuned by changing the concentration of the components. Mol. modeling shows that, when adopting an ideal, extended conformation, the frameworks form an aperture of 4 nm diameter The new flexible frameworks are generally of low cytotoxicity. Fluorescence imaging and flow cytometric anal. demonstrate that the new flexible porous frameworks can quickly include single and double stranded DNA of 21 nucleotides and deliver the included DNA into both normal and cancer cells, with the percentage of delivered cells reaching up to 99.5%.
