Non-technical Summary:With this project, supported by the Solid State and Materials Chemistry Program in the Division of Materials Research, principal investigator (PI) Prof. Natalia Shustova and her research group at the University of South Carolina at Columbia develop crystalline metal-organic framework (MOF) materials for which electronic properties can be modulated through external stimuli, such as light or heat. They also study the fundamental understanding of these materials which elucidates the concept of tailoring material properties upon light irradiation. This in turn advances applications ranging from adaptive lenses and memory storage devices to nonlinear optics, fuel cells, or field-effect transistors. A specific example is that the proposed crystalline photoresponsive materials enable future optoelectronic materials. The research is synergistic with the Materials Assembly and Design Excellence in South Carolina (MADE in SC). In addition to transformative research, PI Shustova also continues the development of the Carolinian Women in Science (Wi-Sci) Supportive Network. The major Wi-Sci goal is to create and grow a network of support for women currently at the Carolinian institutions of higher education, including historically black colleges and universities (HBCUs), and therefore increase opportunities for women to attain at least 50% of the positions projected for STEM disciplines in the Carolinas. The proposed Wi-Sci initiative integrates educational and research opportunities for female students in STEM disciplines. Technical Summary:Achieving control over photoisomerization kinetics through material design is a challenge that must be addressed to advance the fields of optoelectronics or memory and energy storage. However, fundamental principles, that allow for enabling control over photoisomerization kinetics (i.e., achieve reversible and fast material photoresponse) are still vastly underdeveloped. This project, supported by the Solid State and Materials Chemistry Program in the Division of Materials Research, furthers the development of crystalline stimuli-responsive hybrid materials exhibiting tunable and reversible photoisomerization of coordinatively-immobilized stimuli-responsive units as a function of material topology. The research team pursues two routes to assemble photoresponsive MOFs: a) assembly of MOFs from a combination of photochromic ligands, such as diarylethene-based ones, and non-photochromic ligands; and b) photoisomerization through MOF-linker side groups. Extensive photophysical analysis of the resulting photoresponsive frameworks are elucidating structure-property relationships related to electronic structure modulation. Additionally, the project promotes integration of educational and research opportunities for high school, undergraduate, and graduate students, with a special emphasis on women in STEM disciplines.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.

非技术摘要：借助该项目，在材料研究部的固态和材料化学计划的支持下，首席研究员（PI）教授Natalia Shustova教授及其在哥伦比亚大学南卡罗来纳大学开发结晶金属有机框架（MOF）材料的研究小组，通过外部刺激或热量来模拟电子特性的材料。他们还研究了对这些材料的基本理解，这些理解阐明了在光照射下定制材料特性的概念。反过来，从自适应镜头和存储器存储设备到非线性光学元件，燃料电池或现场效应晶体管的应用程序又推进了应用程序。一个具体的例子是，所提出的晶体光反应材料可实现未来的光电材料。这项研究与南卡罗来纳州的材料组装和设计卓越（制造）是协同的。除了变革性研究外，Pi Shustova还继续在科学领域的Carolinian妇女（WI-SCI）支持网络的发展。 Wi-SCI的主要目标是在卡罗来纳州高等教育机构（包括历史悠久的黑人学院和大学（HBCUS））建立和建立对目前在卡罗来纳州高等教育机构的支持网络，因此增加了妇女获得至少50％在carolinas中预计STEM学科的职位的机会。拟议的Wi-SCI倡议将STEM学科中女学生的教育和研究机会融合在一起。技术摘要：通过材料设计实现对光异构化动力学的控制是一个挑战，必须应对推进光电或记忆和能源存储的领域。但是，可以控制光异构动力学的基本原理（即实现可逆和快速材料的光响应）仍然非常不发达。该项目得到了材料研究部的固态和材料化学计划的支持，进一步发展了结晶刺激响应的混合材料的发展，这些混合材料表现出可调和可逆的光异构化，以协调的刺激性刺激反应性单元作为材料拓扑的功能。研究团队追求两条组装光响应MOF的途径：a）来自光致浓度配体（例如基于日记甲基甲基的配体）的MOF组装，以及非光子色素配体； b）通过MOF链侧组的光异构化。对产生的光反应框架进行的广泛的光物理分析是阐明与电子结构调制有关的结构 - 特性关系。此外，该项目促进了高中，本科生和研究生的教育和研究机会的整合，并特别强调了STEM学科中的女性。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准通过评估来获得支持的。
