Summary

Several strategies for preparing thin films based on the synthesis, electrodeposition, and patterning of ultrathin films of conjugated polymer network (CPN) films on flat electrode surfaces using the “precursor polymer” approach will be reviewed. The CPN thin-film approach involves a rational synthesis and design of a precursor polymers followed by electrodeposition and characterization of ultrathin films and coatings on conducting substrates. This can be in the form of direct electrodeposition from solution or the deposition of an ultrathin film on an electrode substrate followed by electropolymerization (or electro-cross-linking). A precursor polymer in CPN essentially contains an electropolymerizable monomer on a linear polymer or dendrimeric backbone that can have “active” or “passive” electro-optical properties. This concept is a departure from previous methods that utilizes small molecular monomers for direct electropolymerization. Characterization of these films can bemade using surface-sensitive spectroscopic andmicroscopic analytical techniques. In addition, electrochemical and impedance analysis methods can be used to investigate electron-transfer and ion-transport properties in this films. Electrochemistry in combination with surface plasmon resonance spectroscopy (SPR) or quartz crystalmicrobalance (QCM), allows their deposition and redox properties to be further quantified. Copolymerization withmonomers, new polymer backbone design, and surface grafting on modified surfaces are the other key points in this thin-film strategy. They have found applications for display devices, sensors, and nanopatterning.
