Exploratory Research on Fabrication and Characterization of Coaxial NanowiresLing ZangDepartment of Chemistry and Biochemistry, Southern Illinois University, Carbondale, IL62901Abstract:The goal of this one-year exploratory project is to develop one-dimensional (1D) self-assembly of macrocyclic molecules that are easily processed into tubular nanomaterials and specifically structured for highly efficient photonic sensing. The molecules to be targeted are arylene-ethynylene macrocycles (AEMs), which possess unique features (such as large p-surfaces and shape-persistence) suitable for 1D self-assembly and optoelectronic applications. The major effort of this project will be made on fabrication of individual nanowires with controllable sizes and coordination with C60, as well as the basic optoelectronic characterization with regard to photonic sensing. The toroidal shape of AEM enables formation of tubular columnar structure with C60 encapsulated inside, leading to formation of spatially segregated N- and P-channels. Such a nano-coax structure possesses intrinsic high efficiency of photoinduced charge separation, which is desired for optoelectronic applications. The proposed research will also be tightened with the PI's ongoing education initiatives in nanoscience.

探索性研究同轴纳米线的制造和表征Ling ZangDepartment of Chemistry and Biochemistry，Southern Illinois University，Carbondale，IL 62901摘要：这个为期一年的探索性项目的目标是开发一维（1D）自组装的大环分子，这些分子很容易加工成管状纳米材料，并专门用于高效的光子传感。 要靶向的分子是亚芳基-亚乙炔基大环（AEM），其具有适合于1D自组装和光电应用的独特特征（例如大的p-表面和形状持久性）。 该项目的主要工作将是制作具有可控尺寸和与C60协调的单个纳米线，以及关于光子传感的基本光电表征。 AEM的环形形状使得能够形成内部封装有C60的管状柱状结构，从而形成空间隔离的N-和P-通道。这种纳米同轴结构具有固有的光致电荷分离的高效率，这是光电应用所期望的。 拟议的研究也将加强与PI的纳米科学正在进行的教育计划。
