Hydrogen-bonded networks design strategies

Using the above strategy for the preparation of layered compounds the next step for the preparation of a layered diacetylene was to design a second molecular structure containing the diacetylene and necessary functionality for its incorporation into the layered hydrogen bonded network [15]. A reasonable choice is diacetylene 2 which contains the pyridine functionality, a functionality well known to hydrogen bond to carboxylic acids forming supramolecular networks [16].
