Pyridinium salts, both molecular and polymeric, are an interesting class of
multifunctional materials that exhibit liquid-crystalline and light-emitting properties.
Moreover, their properties can be easily tuned by introducing new types of anions or by
modifying their chemical structures. This dissertation describes synthesis and
characterization of poly(pyridinium salt)s containing macrocounterions and fluorene
moieties in their backbones, synthesis and characterization of nanocomposites of
poly(pyridinium salt)s with single-walled carbon nanotubes via non-covalent interactions,
and synthesis and characterizations of pyridinium salts having different aliphatic linkages
and their application in organic acid sensing.
First, all of these ionic polymers were prepared by either ring-transmutation or by
metathesis reaction. Their chemical structures were established by FTIR, 1H spectroscopy
and elemental analysis. Some polymers containing macrocounterions had relatively low
melting transitions above which they formed thermotropic liquid-crystalline phase; and
other polymers were amorphous as determined by VTXRD studies. Ionic polymers
containing fluorene moieties in their backbones exhibited lyotropic properties in both
