In recent years, water-soluble conjugated polymers have attained much attention as the optical platform in chemical and biological sensors. In comparison to small molecule counterparts, the electronic structure of the conjugated polymer coordinates the action of a large number of absorbing units. Conjugated polyelectrolytes are polymers containing a π-conjugated backbone and functional groups that ionize in high dielectric media. Conjugated polyelectrolytes offer interesting possibilities for optoelectronic applications, including the formation of surface dipoles, ion motion to compensate injected charges, and solubility in polar solvents to fabricate multilayer structures by alternating solvent polarity with minimum disturbance of underlying layers. Water-soluble conjugated polyelectrolytes can be used as highly sensitive materials in biosensors for aqueous environments in a living body. |
