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
