该奖项授予乔纳森·林赛教授（北卡罗来纳州州立大学）、大卫·博西安教授（加州大学滨江分校）和杜威·霍尔滕教授（华盛顿大学），由化学系先进材料和加工项目提供支持。根据该奖项，新的低聚物将由多金属卟啉，酞菁和二萘嵌苯单元合成。低聚物将通过区域选择性聚合连接以形成环状和纳米管大分子结构，最终目标是由这些结构制造所有的光闸、导电分子线和同轴电缆组件。 光学和电子材料将通过不同的电子物理方法来表征。 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。将根据该研究奖制备圆形和纳米管的光活性和电活性大分子结构。 将制备具有可控网络、取向、尺寸和形状的大环结构，并通过官能化管状和环状结构来制备分子线和同轴电缆。 这些光学和电子材料可能在诸如逻辑门和分子计算机的小型电子器件中有应用。 此外，该研究计划将为材料化学专业的学生提供丰富的多学科教育和培训机会。

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.
