项目摘要

Professor Nicholas Turro, of the Department of Chemistry at Columbia University, is supported by the Organic and Macromolecular Chemistry Program for his studies that will (1) investigate the EPR characterization of the structure and dynamics of molecules adsorbed on the external surface of a series of monodispersed zeolite crystals; (2) study the stereoselectivity of the reaction of singlet oxygen with enecarbamates adsorbed on the internal surface of zeolites; (3) examine the interactions of macromolecules end-labeled with an electronically excited state, a reactive radical or an electron spin polarized state with small molecules (as a model for the propagation step in free radical polymerization) and with the ends of other macromolecular chains (as a model for the termination step in free radical polymerization); and (4) explore the simultaneous absorption of two photons to induce photochemistry with long wavelength light. Each of these research activities will be investigated through a multi-technique approach including time resolved spectroscopic methods (UV-VIS absorption, fluorescence, phosphorescence, infrared, electron paramagnetic resonance and nuclear magnetic resonance).With this Award, the Organic and Macromolecular Chemistry Program continues its support of the research activities of Professor Nicholas J. Turro of Columbia University where in addition to its intrinsic scientific interest, the zeolite characterization project in this proposal is of practical significance given the importance of zeolites as catalysts in various industrial processes. The polymer kinetics project has obvious industrial significance as well. The multiphoton studies could lead to a method of tagging biological macromolecules with fluorescent probes that can be activated in vivo by long wavelength light that is only weakly absorbed by the tissues. Broader impacts of Professor Turro's activities include the integration of research and education through the use of the twin themes of spectroscopy and photochemistry as a conceptual basis for developing chemistry lectures and chemistry laboratories in undergraduate courses. During the past funding period Professor Turro has contributed to diversity in the human resource pool for science by serving as a mentor for 15 graduate students, 23 postdoctoral associates, 10 undergraduates and 3 high school teachers. This group included 11 women and 6 minority students.
哥伦比亚大学化学系的Nicholas Turro教授的研究得到了有机和大分子化学项目的支持,他的研究将(1)研究吸附在一系列单分散沸石晶体外表面上的分子的结构和动力学的EPR表征;(2)研究了单重态氧与吸附在沸石内表面的烯氨基甲酸酯反应的立体选择性;(3)研究末端标记有电子激发态的大分子的相互作用,反应性自由基或小分子的电子自旋极化状态(作为自由基聚合中的增长步骤的模型)和与其它大分子链的末端(作为自由基聚合中终止步骤的模型);和(4)探索两个光子的同时吸收以用长波长光诱导光化学。这些研究活动中的每一个都将通过包括时间分辨光谱方法在内的多技术方法进行研究(紫外-可见吸收、荧光、磷光、红外、电子顺磁共振和核磁共振)。有了这个奖项,有机和高分子化学计划继续支持哥伦比亚大学Nicholas J. Turro教授的研究活动,除了其固有的科学由于沸石在各种工业过程中作为催化剂的重要性,本提案中的沸石表征项目具有实际意义。聚合物动力学项目也具有明显的工业意义。多光子研究可能导致一种用荧光探针标记生物大分子的方法,该荧光探针可以在体内被仅被组织微弱吸收的长波长光激活。Turro教授的活动的更广泛的影响包括通过使用光谱学和光化学的双重主题作为发展本科课程化学讲座和化学实验室的概念基础,将研究和教育结合起来。在过去的资助期间,Turro教授为15名研究生、23名博士后、10名本科生和3名高中教师担任导师,为科学人力资源库的多样性做出了贡献。其中包括11名妇女和6名少数民族学生。
