项目摘要
The Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division supports Prof. George R. Newkome of The University of Akron to investigate fractal nano- and macroscale molecules (self-similar components at differing size scales) based on multicomponent, supramolecular, directed and self-assembly protocols that rely on terpyridine-metal-terpyridine building block connectivity. The ability to incorporate site-specific, multiple metal centers into a predesigned molecular array or network affords a method to fine-tune the desired physical and chemical properties of the molecular fractals. The potential to introduce and exchange differing metals within the fractal framework, either during or after construction, will facilitate the study of precisely designed multimetal ensembles that have ramifications in molecular electronics, self-repairing frameworks, and antenna incorporation at the nanoscopic level. Precise pattern-based molecular structures are also envisioned. Use of these charged, polymetal lattices for composite fiber formation, based on alternating charged species will be investigated with increasingly higher generation fractal-based materials. Physical properties and uses envisioned involve energy storage and release, molecular electronic devices, data storage, solar cell nanocomponents, sensor and optical display capabilities, molecular antennas, and metamaterials.New materials comprised of repeating similar shapes of differing sizes (termed "fractal") held together by metal glue-like interactions will be assembled, based on their components interactions, such as their potential to fit, pack, and associate in an orderly manner. This will lead to new types of macromolecules for use in electronic devices and components, such as with batteries for energy storage, switches in electric circuits, and antennas in miniature communication devices. Educational opportunities arise from the training and development of students and scientists at all academic levels. Educational outreach is promoted through regular presentations at regional, national and international public and private schools, universities, and conferences. Industrial and international collaborations continue to enhance this research through personnel and information exchange.
化学学部的大分子、超分子和纳米化学项目支持阿克伦大学的George R. Newkome教授基于多组分、超分子、定向和自组装协议研究分形纳米和宏观分子(不同尺寸的自相似成分),这些协议依赖于三联吡啶-金属-三联吡啶构建块连接。将特定位置的多个金属中心整合到预先设计的分子阵列或网络中的能力提供了一种微调分子分形所需的物理和化学性质的方法。在分形框架内引入和交换不同金属的潜力,无论是在构建过程中还是之后,都将有助于研究精确设计的多金属集成体,这些集成体在分子电子学、自我修复框架和纳米级天线集成方面具有分支。精确的基于模式的分子结构也被设想。利用这些带电的多金属晶格来形成基于交变带电物质的复合纤维,将随着越来越多的分形基材料的出现而得到研究。所设想的物理性质和用途包括能量存储和释放、分子电子设备、数据存储、太阳能电池纳米组件、传感器和光学显示能力、分子天线和超材料。由重复的不同大小的相似形状(称为“分形”)组成的新材料将通过金属胶状相互作用结合在一起,基于它们的组件相互作用,例如它们以有序的方式装配,包装和联想的潜力。这将导致用于电子设备和组件的新型大分子,例如用于储能的电池,电路中的开关和微型通信设备中的天线。教育机会来自对各级学术水平的学生和科学家的培训和发展。通过在地区、国家和国际公立和私立学校、大学和会议上的定期演讲来促进教育外展。通过人员和信息交流,工业和国际合作继续加强这方面的研究。
