Photochemical Studies of Multicomponent Molecular Devices inSolution and in Organized Assemblies

在有机动力学计划和数学与物理科学理事会多学科活动办公室的支持下，亚利桑那州立大学化学与生物化学系的J. Devens Gust, Jr.教授和Thomas A. Moore教授正在进行溶液和有组织组装中的多组分分子器件的光化学研究。天然光合反应中心是分子尺度的光伏器件，决定反应中心运行的原理为合成光电开关提供了设计元素。新型颜料和电子供体和受体基团，包括功能化巴克敏斯特富勒烯、芳香亚胺和胺，以及卟啉衍生物，正被用于构建分子尺度的光伏、开关和逻辑门。仿生天线系统，收集光和传输激发能这些分子光伏和开关也将被研究。将开关整合到更大规模的设备中，将通过将分子物种与微电子电路连接以及将分子光伏整合到脂质体中来研究。亚利桑那州立大学化学与生物化学系的J. Devens Gust, Jr.教授和Thomas A. Moore教授得到了有机动力学项目和数学与物理科学理事会多学科活动办公室的支持，他们研究了旨在收集光能的分子和分子组装。古斯特教授和摩尔教授根据自然界设计的进行光合作用过程的结构母题，制备并研究吸收和利用光能的分子。通过适当的分子系统设计，这些研究解决了分子与光相互作用背后的基本现象，同时为制备分子尺度的电子和计算设备铺平了道路，这些设备提供了光学处理和超高密度信息存储的可能性。

With the support of the Organic Dynamics Program and the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate, Professor J. Devens Gust, Jr. and Professor Thomas A. Moore, of the Department of Chemistry and Biochemistry at Arizona State University, are carrying out photochemical studies of multicomponent molecular devices in solution and in organized assemblies. Natural photosynthetic reaction centers are photovoltaic devices of molecular dimensions, and the principles dictating the operation of reaction centers suggest design elements for synthetic optoelectronic switches. New types of pigments and electron donor and acceptor moieties, including functionalized buckminsterfullerenes, aromatic imides and amines, and porphyrin derivatives, are being used to construct molecular-scale photovoltaics, switches, and logic gates. Biomimetic antenna systems that gather light and transport excitation energy to these molecular photovoltaics and switches will also be studied. Incorporation of switches into larger-scale devices will be examined both by interfacing molecular species with microelectronic circuits and by incorporation of molecular photovoltaics into liposomes. Professor J. Devens Gust, Jr. and Professor Thomas A. Moore, of the Department of Chemistry and Biochemistry at Arizona State University, are supported by the Organic Dynamics Program and the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate for their studies of molecules and molecular assemblies designed to harvest the energy of light. Modeling their studies after the structural motif designed by nature to carry out the process of photosynthesis, Professors Gust and Moore prepare and study molecules which absorb and use the energy of light. By appropriate design of molecular systems, these studies address the fundamental phenomena behind such interactions of molecules with light while paving the way for the preparation of molecular-scale electronic and computational devices which offer the possibility of optical processing and extraordinarily high density storage of information.
