Synthesis Of Conducting Polymers Functionalized With Oxetane Methanol Monomer

Conjugated polymers continue to attract great interest of many scientists. At present,there are two methods to preapare conducting polymers, chemical and electrochemicalmethods. And electrochemical polymerization has been tested as one of the most effectiveway for the prepration of high-quanlity conducting polymers, its advantage is that the processis simple, easy to operate, with less, without catalyst. With the development of science andtechnology, conductive polymer materials are fully utilized in electroluminescent devices,promoting the application and development of organic semiconductors. Polythiophenes (PTs)and their derivatives, as a class of conducting polymers, have attracted considerable attentiondue to their good conductivity and chemical stability. Because of their highly efficientphotoluminescence and electroluminescence, thermal and oxidative stability, good solubility,and emission of polarized blue light, they are especially suitable for applications to polymerlight emitting diodes. This dissertation mainly focused on the electrosynthesis of a noveloxetane-functionalized cross-linkable conjugated polymer, and characterization ofhigh-quality conducting polymers.1. A novel oxetane methanol functionalized with pendant thiophene monomer(TO) wasdesigned and successfully synthesized. Precursor polymers were prepared by the radicalpolymerization of the monomer. High quality freestanding polyfluorene network films weresynthesized successfully in CH2Cl2containing additional25%(by volume) BFEE by directanodic oxidation. UV-visible and FT-IR spectra and TGA were used to study the structures ofthe polymers, respectively.2. Copolymer PPTOF were prepared by the radical polymerization of the monomer. Highquality freestanding network films were synthesized successfully in CH2Cl2containingadditional25%(by volume) BFEE by direct anodic oxidation. UV-visible and FT-IR spectraand TGA were used to study the structures of the polymers, respectively.3. Copolymer PPTOM were prepared by the radical polymerization of the monomer. Highquality freestanding network films were synthesized successfully in CH2Cl2containingadditional25%(by volume) BFEE by direct anodic oxidation. UV-visible and FT-IR spectra and TGA were used to study the structures of the polymers, respectively.4. Copolymer PPTOC were prepared by the radical polymerization of the monomer.
