This project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Professor Mikhail Barybin of the University of Kansas will study charge delocalization and transport within the 2,6-azulenic framework. The approach is to synthesize novel azulenic and bis-azulenic molecules linearly terminated with isocyano, mercapto, or cyano groups; to form and characterize self-assembled monolayer (SAM) films and nanografted patterns of these compounds on metal surfaces; to synthesize and study discrete metal complexes of these ligands to understand the ligand interactions with metal ions; and to probe the conductivity of the azulenic and bis-azulenic SAM films The broader impacts involve training undergraduate and graduate students in an interdisciplinary research environment, developing a new freshman honors course on the "Nanotech Revolution," and working with Northeastern State University (a predominantly Native American student institution) to bring students to the University of Kansas for undergraduate research experiences.Computing using molecules has the potential to generate ultrasmall devices that use little power; however, many significant technical hurdles must be overcome to realize the benefits of molecular level devices. This work will further our understanding how molecules transport charges between two contacts and will afford novel platforms for developing advanced materials relevant to a variety of nanotechnological areas, including organic electronics. Such work could also impact the design of solar cells, molecular switches, and conducting polymers.

该项目由堪萨斯大学的Mikhail Barybin教授化学系的大分子，超分子和纳米化学项目资助，将研究2，6-azulenic框架内的电荷离域和传输。该方法是合成新型的azulenic和bis-azulenic分子，其线性末端为异氰基、巯基或氰基;形成和表征这些化合物在金属表面上的自组装单层（SAM）膜和纳米接枝图案;合成和研究这些配体的离散金属络合物以理解配体与金属离子的相互作用;并探测天蓝和双天蓝SAM膜的导电性。更广泛的影响包括在跨学科研究环境中培训本科生和研究生，开发关于“纳米技术革命”的新的新生荣誉课程，“与东北州立大学合作（一所以美国原住民学生为主的机构），将学生带到堪萨斯大学进行本科研究体验。使用分子进行计算有可能产生超小型设备，耗电量很小;然而，要实现分子级器件的益处，必须克服许多重大的技术障碍。 这项工作将进一步了解分子如何在两个触点之间传输电荷，并为开发与各种纳米技术领域（包括有机电子学）相关的先进材料提供新的平台。 这项工作也可能影响太阳能电池、分子开关和导电聚合物的设计。
