In this project in the Advanced Materials and Processing Program of the Chemistry Division, Dr. Michael Krische of the Department of Chemistry and Biochemistry of the University of Texas at Austin will design and synthesize conjugated macromolecular structures formed by interstrand hydrogen bonding. Co-facial alternate stacking of bis-thiophene and fluorene chromophores will produce stable conducting materials with efficient charge transport properties. Using other starting materials, duplex macromolecular materials may be synthesized for applications in molecular storage devices, catalysts and self-replicators. Planned centralized organic chemistry centers with 'virtual' (on-line) and 'real' accessibility will provide the undergraduate students with instructional materials and career development opportunities including graduate programs and job openings.Abiotic duplex polymer structures modeled after DNA will be synthesized using different starting materials. These macromolecular structures formed by inter-molecular hydrogen bonding will be useful as conducting materials with high charge transfer properties. Centralized learning centers in the chemistry department with on-line accessibility will be a new instructional tool to students in materials chemistry.

在化学部先进材料与加工项目的这个项目中，德克萨斯大学奥斯汀分校化学与生物化学系的Michael Krische博士将设计并合成由链间氢键形成的共轭大分子结构。 双噻吩和芴发色团的共面交替堆叠将产生具有高效电荷传输特性的稳定导电材料。 使用其他起始材料，可以合成双链高分子材料，用于分子存储装置、催化剂和自复制器。 计划中的集中式有机化学中心具有“虚拟”（在线）和“真实”的可访问性，将为本科生提供教学材料和职业发展机会，包括研究生课程和职位空缺。以 DNA 为模型的非生物双链聚合物结构将使用不同的材料合成。起始材料。 这些由分子间氢键形成的大分子结构将可用作具有高电荷转移性能的导电材料。 化学系的集中学习中心可在线访问，这将成为材料化学学生的新教学工具。
