水醇溶有机/聚合物光电材料的研究

In this proposal, we devote to develop new water / alcohol soluble conjugated polymers (WSCPs), which can be used for high-performance organic electronic devices. To reveal the mechanism of such WSCPs as interfacial materials in multi-layer optoelectronic devices, we will perform systematically investigation on the effects of backbones, side chains, counterions and the film morphology on the optoelectronic properties of devices. On the basis of the aforementioned studies and the established relationships among chemical structures, aggregations in solid state and device performances, we would dedicate to design and synthesize new WSCPs that can be solution-processed by environment-friendly solvents, which are supposed to be appropriate for the applications toward the production of large-area devices including organic/polymer light-emitting diodes and polymer solar cells. The integration of multi-discipline studies including material synthesis, device engineering and device physics, makes it possible to get breakthrough in developing new WSCPs and their relevant applications in large-area devices. We believe the potential achievements in this proposal would significantly contribute to the future industrialization of novel printing processed displays and low-cost, highly-efficient renewable energy technology of our country.
