Self-organized supramolecules of poly(2,5-pyridinediyl)

Polypyridines are remarkably stable and good charge transport materials having high photoluminescence quantum yield. They form supramolecules that form lamellar self-organized structures due to bonding between pyridine and sulphonic acid unit and polar nonpolar effects combined. Some examples are demonstrated here using synchrotron radiation and small angle X-ray scattering (SAXS) method.
