Optical, Electrochemical, and Electrical Properties of Novel Conjugated Oligomers and Polymers.Conjugated polymers have received a lot of attention from both academic and industrial laboratories since they combine the best features of metals or inorganic materials with those of synthetic plastics. This synergy not only makes these new materials useful in existing electronic and optical devices (light-emitting diodes, transistors, solar cells, etc.) but also creates completely new opportunities. Along these lines, we intend to synthesize and characterize new electroactive and photoactive polymeric supports for the direct and specific detection of proteins, cells, etc. This project should lead to the development of novel efficient and simple tools for biomedical research. In another project, we plan to develop ionic nitrogen-containing conjugated polymers.  It is anticipated that these usually amorphous materials may self-assemble through non-covalent interactions to yield well-organized pi-stacked supramolecular structures.  Pi-stacking is an important feature to improve the electrical transport in these organic materials. For instance, these studies should contribute to the design of more efficient transistors and solar cells. Finally, we propose to design, synthesize, and characterize completely new conjugated oligomers and polymers incorporating unusual heteroatoms (B, Ga, In, etc.). These hybrid polymers should exhibit interesting and tunable physical properties. In particular, stable negative charge carriers should be created upon electrochemical or acid-base reactions.All these studies should therefore shed some light on the physical properties of new conjugated oligomers and polymers within different integrated molecular systems. This work should pave the way to the development of novel biosensors and plastic electro-optical devices.

新型共轭低聚物和聚合物的光学、电化学和电学性质。共轭聚合物结合了金属或无机材料与合成塑料的最佳特性，因此受到了学术界和工业实验室的广泛关注。这种协同作用不仅使这些新材料在现有的电子和光学器件（发光二极管、晶体管、太阳能电池等）中有用，而且还创造了全新的机会。沿着这些思路，我们打算合成和表征新的电活性和光活性聚合物载体，用于直接和特异性检测蛋白质，细胞等。这个项目应该导致开发新的高效和简单的生物医学研究工具。在另一个项目中，我们计划开发含氮离子共轭聚合物。预计这些通常无定形的材料可以通过非共价相互作用自组装，从而产生组织良好的pi堆叠超分子结构。pi堆积是改善这些有机材料电输运的一个重要特征。例如，这些研究应该有助于设计更高效的晶体管和太阳能电池。最后，我们建议设计、合成和表征包含不寻常杂原子（B、Ga、In等）的全新共轭低聚物和聚合物。这些杂化聚合物应该表现出有趣和可调的物理性质。特别是，在电化学反应或酸碱反应中应产生稳定的负电荷载体。因此，所有这些研究应该对不同集成分子体系中新的共轭低聚物和聚合物的物理性质有所启发。这项工作将为新型生物传感器和塑料光电器件的发展铺平道路。
