The research group of Jean-Hubert Olivier at The University of Miami seeks to develop new strategies to manipulate the interactions of organic molecules and polymers in nanoscale architectures (with dimensions of 1/1,000,000 meter). The overarching goal is to understand how one can precisely control assembly pathways to reconfigure the structure of organic materials and promote efficient energy transport. The results of this fundamental research have implications in solar cell design and optoelectronic devices. This project also nurtures the development of training platforms to prepare students to tackle social challenges and complex scientific problems. To achieve these goals, the Olivier group develops a Science Discovery Program: “Create and Assemble: How Nature Builds “Stuff””. The program seeks to ignite a curiosity for science and technology in younger generations, creates an environment that promotes critical thinking, motivates students across all age groups to pursue scientific careers, and sensitizes a more mature audience to the extent to which science and education can greatly contribute to a more sustainable future.With the support of the Macromolecular, Supramolecular, and Nanochemistry Program of the NSF Division of Chemistry, this project develops a new set of tools to navigate the aggregation free-energy landscape and create energetically trapped architectures equipped with structure-function properties unattainable at equilibrium. The Olivier groups seeks to establish rules and principles to manipulate the electronic structures of π-conjugated building blocks and form out-of-equilibrium states (n-doped) to tune the non-covalent interactions between superstructure precursors. From solution-phase studies that exploit spectroscopy and electrochemistry, this project seeks to understand how reconfigured superstructures promote exciton delocalization and transport. Furthermore, strategies are being developed to “lock-in” supramolecular architectures both at equilibrium, and when placed out-of-equilibrium (n-doped). Well-defined nanoscale objects created in this manner unearth a new understanding of the electronic properties enforced by electronically perturbed out-of-equilibrium states. Rules and principles are elucidated to enable, at the solid/liquid interface, the formation of hierarchical nanostructures derived from energetically trapped superstructures.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

迈阿密大学的让·赫伯特·奥利维尔（Jean-Hubert Olivier）研究小组旨在制定新的策略，以操纵纳米级体系结构中有机分子和聚合物的相互作用（尺寸为1/1,000,000米）。总体目标是了解如何准确控制组装途径以重新配置有机材料的结构并促进有效的能源运输。这项基本研究的结果对太阳能电池设计和光电设备具有影响。该项目还护理了培训平台的发展，以准备学生应对社会挑战和复杂的科学问题。为了实现这些目标，奥利维尔集团开发了一项科学发现计划：“创建和组装：自然如何建立“东西”。该计划试图激发对年轻一代的科学和技术的好奇心，创造了一个促进批判性思维的环境，激励所有年龄段的学生从事科学职业，并感知到更成熟的受众，以至于科学和教育可以很好地促进更可持续的未来，并在多大程度上促进了大分子，超级分子的一项计划。浏览聚合的自由能景观并创建有效捕获的结构，配备了在平衡时无法实现的结构 - 功能。奥利维尔（Olivier）群体试图建立规则和原则，以操纵π共轭构件的电子结构，并形成平衡状态（n掺杂），以调整上层结构前体之间的非共价相互作用。从利用光谱和电化学的解决方案相研究，该项目试图了解重新配置的上层建筑如何促进令人兴奋的分类和运输。此外，正在制定策略以平衡以“锁定”超分子体系结构，以及放置在平衡外（N掺杂）时。定义明确的纳米级对象以这种方式创建了对电子扰动的不平衡状态强制执行的电子特性的新理解。规则和原则被阐明以在固体/液体界面上启用，从本质上被困的上层建筑衍生出的层次纳米结构的形成。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来通过评估来诚实地支持。
