项目摘要

The Advanced Materials Program in the Division of Chemistry makes this award to University of California San Diego. With the award, Professor William Trogler will study different methods such as photochemistry, chemical reduction, electro-polymerization and thermal polymerization to prepare new layered polymeric materials based on carbon diselenides, which will be free from elemental selenium. Doped thin films prepared from poly (carbonselenide)s will be studied for electrochemical, electronic conductivity and chemical redox properties. Complexation of cadmium with poly (carbondiselenide) at the surface would produce cadmium selenide nanoparticles and quantum dots with unique optical and electronic properties for potential applications in devices. New polymeric materials based on carbon selenides and cadmium selenide quantum dots with electronic and photonic properties will be prepared. Synthetic methods to prepare poly (carbondiselenide)s free from elemental selenium and physical methods to characterize these materials would provide basic science knowledge for the future development of new electronic and photonic materials. Doped thin and flexible films of carbon diselenides would have unique electronic and photonic properties for applications in devices. The research, in addition, will provide training to graduate students in electronic and photonic materials.

化学系的先进材料计划将此奖项授予加州圣地亚哥大学。凭借该奖项，William Trogler教授将研究不同的方法，如光化学，化学还原，电聚合和热聚合，以制备基于碳二硒化物的新型层状聚合物材料，该材料将不含硒元素。掺杂的聚（硒化碳）的薄膜制备的电化学，电子导电性和化学氧化还原性能进行了研究。镉与聚（碳二硒）在表面的络合将产生具有独特的光学和电子性质的硒化镉纳米颗粒和量子点，在器件中具有潜在的应用。基于硒化碳和硒化镉量子点的新型聚合物材料将被制备成具有电子和光子特性的材料。研究制备不含硒元素的聚碳二硒化合物的合成方法和表征这些材料的物理方法，将为未来新型电子和光子材料的开发提供基础科学知识。掺杂的碳二硒化物薄膜和柔性薄膜将具有独特的电子和光子特性，可用于器件中。此外，这项研究还将为电子和光子材料的研究生提供培训。
