The Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division supports the research group of Professor Jonathan Sessler of the University of Texas at Austin on a project that involves the chemistry of expanded porphyrins and related heterocyclic macrocycles. Particular emphasis will be placed on new, electron deficient macrocycles whose electronics are "reversed" compared to those of most expanded porphyrins. These new systems are expected to display interesting molecular recognition properties and act as building blocks for the construction of higher order supramolecular assemblies. This will permit the construction of self-assembled organometallic frameworks, supramolecular organic frameworks, threaded pseudorotaxanes, and self-assembled electron transfer ensembles, among other possibilities. The new molecular and supramolecular materials prepared in the context of this project are expected to be environmentally responsive and to respond to more than one analyte. It is likely that new chemical entities with broad utility will emerge from this program and be explored by commercial entities. Work in this area contributes to the development of the nation's technological infrastructure. Work in the synthetic porphyrin analogue area is highly interdisciplinary. It involves aspects of organic synthesis, inorganic chemistry, spectroscopy, materials science, catalysis, and supramolecular chemistry. It provides excellent training for young researchers who are then able to work in a variety of settings, including academe, industry, and government. The collaborations with other research groups contribute to the broader impact of the work and provide educational opportunities for the students involved in the project. Collaborative research experience with overseas collaborators is highly beneficial and is contributing to the development of a stronger, scientifically and culturally literate human resource base in the U.S.

化学部的大分子，超分子和纳米化学计划支持德克萨斯大学奥斯汀分校的乔纳森·塞斯勒（Jonathan Sessler）教授的研究小组，该小组涉及一个涉及扩展的卟啉和相关杂环杂种型大环的化学反应。 与大多数扩展的卟啉相比，其电子设备被“反向”的新型，不足的大型大环将特别强调。预计这些新系统将显示出有趣的分子识别特性，并充当建造高阶超分子组件的基础。这将允许构建自组装有机金属框架，超分子有机框架，螺纹伪驱动器以及自组装的电子传输团体，以及其他可能性。在该项目背景下制备的新分子和超分子材料预计将对环境响应，并响应多个分析物。具有广泛实用性的新化学实体可能会从该计划中出现，并由商业实体探索。 该领域的工作有助于国家技术基础设施的发展。 合成卟啉类似物区域的工作是高度跨学科的。 它涉及有机合成，无机化学，光谱，材料科学，催化和超分子化学的各个方面。它为年轻的研究人员提供了出色的培训，这些研究人员可以在包括学术界，工业和政府在内的各种环境中工作。 与其他研究小组的合作为工作的广泛影响做出了贡献，并为参与该项目的学生提供了教育机会。 与海外合作者的合作研究经验非常有益，并为在美国建立更强大，科学和文化的人力资源基础做出了贡献
