标 题:Electrochemical synthesis and processing of conducting polymers in supercritical media

摘要:The present invention deals with the electrochemical synthesis of electrically conductive polymers in supercritical fluids, for example supercritical CO 2 . The use of the supercritical fluid as a solvent results in the reduction or elimination of hazardous reagents and environmentally hazardous waste, which was generated in the prior chemical synthesis techniques. The electrochemical approach eliminates the need to add a charge transfer agent as the electrode serves this purpose. The resulting polymers are characterized by high conductivities and distinctive surface morphology, which suggests that they may be more appropriate than the previous materials for certain applications (e.g., corrosion inhibition, optical applications, etc.).

摘要:Synthesis of lyotropic semiconducting polymers having novel side chains enabling control over crystalline fraction, crystalline orientation, and the unit cell (specifically the Ï€-stacking distance). Moving the branch point in the side chain further from the conjugated backbone not only retains the lyotropic liquid crystalline behavior as observed by UV-vis and POM, but also achieves reduced Ï€-stacking distance. This results in higher charge carrier mobility, reaching (in one or more examples) a mobility of at least 0.41 cm 2 V −1 s −1 when the polymers were non-aligned.

摘要:A method of fabricating a composition of matter, including fabricating one or more conjugated polyelectrolytes each comprising a donor-acceptor copolymer backbone and one or more anionic side groups, wherein the one or more conjugated polyelectrolytes are self doped. The doped conjugated polyelectrolytes can be used in a hole transport layer in a solar cell.

摘要:In various embodiments, chromophores are described that include novel electron acceptors, novel electron donors, and/or novel conjugated bridges that are useful in nonlinear optical applications. In some embodiments, the present invention provides chromophore architectures wherein a chromophore contains more than one electron acceptor in electronic communication with a single electron donor, and/or more than one electron donor in electronic communication with a single electron acceptor. Also described are processes for providing materials comprising the novel chromophores and polymer matrices containing the novel chromophores. Electro-optic devices described herein contain one or more of the described electron acceptors, electron donors, conjugated bridges, or chromophores.
