Photonic, Electronic, and Optoelectronic Materials for Molecular Devices

授予乔纳森·林赛(北卡罗来纳州立大学)、David Bocian(加州大学河滨分校)和Dewey Holten(华盛顿大学)教授的这一奖项得到了化学部先进材料和加工计划的支持。根据该奖项，新的低聚物将由多金属卟啉、酞菁和戊二烯单元合成。低聚物将通过区域选择性聚合连接起来，形成环状和纳米管大分子结构，最终目标是用这些结构制造所有的光门、导电分子线和同轴电缆组件。光学和电子材料将用不同的光物理方法进行表征。将进行光激发研究，以确定这些材料中能量和电荷分布的速率和效率。根据该研究奖，将制备光活性和电活性大分子结构，包括圆形和纳米管。通过对管状结构和环状结构进行功能化处理，制备出具有可控网络、取向、大小和形状的大环结构，以及分子导线和同轴电缆。这些光学和电子材料可能在小型电子设备中有应用，如逻辑门和分子计算机。此外，该研究项目将为学生提供丰富的多学科材料化学教育和培训机会。

This award to Professors Jonathan Lindsey (North Carolina State University), David Bocian (University of California Riverside) and Dewey Holten (Washington University) is supported by the Advanced Materials and Processing Program in the Chemistry Division. Under the award, new oligomers will be synthesized from multimetallic porphyrins, phthalocyanines and perylene units. The oligomers will be linked by regioselective polymerization to form cyclic and nanotube macromolecular structures with an ultimate goal of fabricating all optical gates, electrically conducting molecular wires and coaxial cable assemblies from these structures. The optical and electronic materials will be characterized by different photophysical methods. Photoexcitation studies will be carried out to determine the rates and efficiencies of energy and charge distributions in these materials.Photoactive and electroactive macromolecular structures, both circular and nanotubular, will be prepared under this research award. The macrocyclic structures with controlled networks, orientation, size and shape will be prepared, and molecular wires and coaxial cables will be fabricated by functionalizing the tubular and cyclic structures. These optical and electronic materials may have applications in small electronic devices such as logic gates and molecular computers. In addition, the research program will provide a rich multidisciplinary education and training opportunity to students in material chemistry.
