This GOALI award, co-funded by the Division of Materials Research and the Office of Multidisciplinary Activities of the Directorate for Mathematical & Physical Sciences, involves a collaboration between the University of Rochester and the Eastman Kodak Company. A new concept for photoresponsive polymers is described based on a process called Quantum Amplified Isomerization (QAI). QAI materials are defined as polymers that undergo electron transfer-initiated ion radical chain isomerization reactions upon absorption of light. QAI materials have the potential to overcome many of the known problems associated with existing photoresponsive polymers, while still retaining their primary advantages. Specifically, QAI materials are designed to produce many chemical tranformations per photon absorbed, with little or no accompanying dimensional changes. The primary research goals of this proposal are: (1) to obtain a predictive understanding of the fundamental ion radical chain reaction chemistry that forms the basis of QAI processes, (2) to test sensitization strategies for the efficient inititaion of QAI processes, (3) to use the insights from (1) and (2) to design and synthesize functionalized QAI polymers, and (3) to characterize key optical properties of new QAI materials.This collaboration is in the fields of photochemistry and optical materials for communications, and involves a number of educational experiences, including on-site industrial research for the students and weekly group meetings among the academic and industrial co-PI's.

该目标奖由材料研究部和数学和物理科学局的多学科活动办公室共同资助，涉及罗切斯特大学与伊士曼柯达公司之间的合作。 基于称为量子扩增的异构化（QAI）的过程描述了一个新的光反应聚合物概念。 QAI材料被定义为在吸收光线后经历电子传递引起的离子自由基异构化反应的聚合物。 QAI材料有潜力克服与现有光反应聚合物相关的许多已知问题，同时仍保留其主要优势。 具体而言，QAI材料旨在每光子吸收的每个光子产生许多化学变形，而几乎没有伴随的尺寸变化。 该提案的主要研究目标是：（1）获得对构成QAI过程基础的基本离子激进链反应化学的预测理解，（（2）测试QAI过程有效启动的敏感性策略，（3）使用（1）和（2）和（2）的QAI Poligiane Qai Poligiane Qai Poligiane Qai Poligiane Qai Poligiane Quiairized Qai Poligiaigatizan Qai Poligiaigatizan Qai Poligiaigation fortial tocripatientals和（3）材料。此合作是在光化学和通信的光学材料领域中，涉及许多教育经验，包括针对学生的现场工业研究以及学术和工业Co-Pi之间的每周小组会议。
