Polypyridines are remarkably stable and good charge transport materials hav
ing high photoluminescence quantum yield. They form supramolecules that for
m lamellar self-organized structures due to bonding between pyridine and su
lphonic acid unit and polar nonpolar effects combined. Some examples are de
monstrated here using synchrotron radiation and small angle X-ray scatterin
g (SAXS) method.
