标 题:Electrochemical synthesis and processing of conducting polymers in supercritical media
发明人：MABROUK PATRICIA ANN
权利人:UNIV NORTHEASTERN
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.).

标题 :Branch point effect on structure and electronic properties of conjugated polymers

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.
