With this CAREER Award, the Chemical Structure, Dynamics, and Mechanisms Program supports Professor Jason G. Gillmore of Hope College in a project directed toward the development of electron deficient photochromic molecules that can be used as oxidizing agents in their long-wavelength absorbing photochemically excited state. The project will involve undergraduate researchers in the design of the modified photochromes, their synthesis, and their basic photochemical and electrochemical characterization. The effectiveness of the photochromes in several cationic polymerization and small molecule isomerization reactions will be investigated. The goal is to generate a library of photochromatic materials with varying excited state reduction potentials. This primarily experimental project will also include a computational component. The research by Professor Gillmore develops gated photoinduced charge transfer by synthesizing photochromes that isomerize between short- and long wavelength absorbing states. Broader impacts could lead to applications in photoinitiation of polymerization, data storage, and increased control of chemical reactions. Another important impact of this research will be the exposure of students to topics including electron transfer, ion radical reactive intermediates, photochemistry, cyclic voltammetry, polymerization, materials science, and computational chemistry. Professor Gillmore will implement a full Peer-Led Team Learning program into the organic lecture curriculum. The PI will also hold regional workshops for postdoctoral students who are considering teaching careers at undergraduate institutions.

有了这个职业奖，化学结构，动力学和机制计划支持教授贾森G。Gillmore博士在一个项目中，该项目旨在开发缺电子光致变色分子，该分子可在其长波长吸收光化学激发态下用作氧化剂。该项目将涉及本科研究人员在改性的光致变色剂的设计，合成，其基本的光化学和电化学表征。将研究光致变色剂在几种阳离子聚合和小分子异构化反应中的有效性。目标是产生具有不同激发态还原电位的光致变色材料库。这个主要是实验性的项目也将包括一个计算组件。Gillmore教授的研究通过合成在短波长和长波长吸收状态之间异构化的光致变色物来开发门控光诱导电荷转移。更广泛的影响可能会导致在光引发聚合，数据存储和增加控制化学反应的应用。这项研究的另一个重要影响将是学生接触的主题，包括电子转移，离子自由基反应中间体，光化学，循环伏安法，聚合，材料科学和计算化学。吉尔摩教授将实施一个完整的同行领导的团队学习计划到有机讲座课程。PI还将为正在考虑在本科院校从事教学职业的博士后学生举办区域研讨会。
