The Chemical Structure, Dynamics and Mechanisms Program in the Chemistry Division at the National Science Foundation supports Professor Daniel Falvey of the University of Maryland- College Park, for the development of new molecular systems with controllable photochemical release of one or more functional groups. The goal of the project is to develop donor-acceptor systems that will undergo electron transfer sensitized reactions that release stable molecules such as carboxylic acids. An innovative feature of Professor Falvey's approach is that the molecules will be designed to undergo these reactions after absorbing two photons, so that low energy visible light can be employed. These reactions are important to many fields as they allow for both temporal and spatial control of the movement of molecules. Broader impacts of the research include the potential for improved control of 3D nanofabrication processes, and for imaging and biomedical applications. Professor Falvey is recognized for his breadth of knowledge across several disciplines (organic synthesis, spectroscopy, kinetics, and computational chemistry), which makes his laboratory effective in tackling difficult research problems. He has been successful in recruiting and mentoring underrepresented groups to his laboratory at the University of Maryland, and he is an advisor to the International Chemistry Olympiad.

国家科学基金会化学部的化学结构、动力学和机理计划支持马里兰大学学院园区的丹尼尔·法尔维教授开发具有一个或多个官能团的可控光化学释放的新分子系统。该项目的目标是开发供体-受体系统，该系统将经历电子转移敏化反应，释放稳定的分子，如羧酸。法尔维教授方法的一个创新特征是，分子将被设计为在吸收两个光子后进行这些反应，因此可以使用低能量可见光。这些反应对许多领域都很重要，因为它们允许在时间和空间上控制分子的运动。这项研究的更广泛影响包括改进3D纳米制造过程控制的潜力，以及成像和生物医学应用。法尔维教授因其在几个学科(有机合成、光谱学、动力学和计算化学)方面的广博知识而受到认可，这使得他的实验室能够有效地解决棘手的研究问题。他在马里兰大学的实验室成功地招募和指导了代表人数不足的团体，他是国际化学奥林匹克竞赛的顾问。
