This project addresses the design and synthesis of zeolite-like frameworks based on assembly of Archimedean polyhedra constructed from hydrogen-bonded molecular tiles and related molecular frameworks to create a new family of microporous molecular frameworks with structures and properties that can be modified through choice of molecular constituents. These frameworks are used as scaffolds that encapsulate functional molecules such as laser dyes as well as templates for synthesis of nanoreticulated metal oxides that replicate the topology of the zeolite-like frameworks. This work also capitalizes on the unique ability of lamellar GS compounds to form high quality thin films with controlled two-dimensional packing of conjugated guest molecules with adjustable electronic properties for a systematic examination of electron transport in a field effect transistor configuration.The motivation for this project is driven by promise of new materials that capitalize on the versatility of organic synthesis, which permit manipulation of properties through molecular design. The project explores the synthesis of materials for a new generation of solid-state lasers as well as the molding of nanomaterials with unique electronic properties that can impact technologies ranging from displays to solar energy. The project also provides summer research experiences for undergraduates and faculty from minority-serving and four-year institutions, research experiences for high school students, exposure of students and postdocs to the industrial section through the NYU University Chapter of the Chemists' Club, and professional development opportunities for students and postdocs that will prepare them for careers in science and engineering.

该项目旨在设计和合成基于阿基米德多面体组装的沸石样框架，该多面体由氢键分子瓦和相关分子框架构成，以创建一个新的微孔分子框架家族，其结构和性能可以通过选择分子成分进行修改。 这些框架用作封装功能分子如激光染料的支架以及用于合成复制沸石样框架的拓扑结构的纳米网状金属氧化物的模板。 这项工作还利用了层状GS化合物形成高质量薄膜的独特能力，该薄膜具有可调节电子特性的共轭客体分子的受控二维堆积，用于场效应晶体管配置中电子传输的系统检查。该项目的动机是由利用有机合成的多功能性的新材料的前景驱动，其允许通过分子设计操纵性质。 该项目探索了新一代固态激光器材料的合成，以及具有独特电子特性的纳米材料的成型，这些特性可以影响从显示器到太阳能等技术。 该项目还为来自少数民族服务机构和四年制机构的本科生和教师提供暑期研究经验，为高中生提供研究经验，通过纽约大学化学家俱乐部分会让学生和博士后接触工业部门，为学生和博士后提供专业发展机会，为他们在科学和工程领域的职业生涯做准备。
