Photophysical Investigations of Hydrogen Bonded Complexes in Solution

9303817穆格·理查德·S·穆格得到了理论和计算化学计划的资助，用于进行凝聚相光谱研究。我们将进行两条研究路线。第一项研究将比较香豆素102染料在非极性十氢萘中的旋转重定向和在氟化醇中的重定向寿命，以了解氢键对重定向时间的影响。第二个研究将考察氢键1-氮杂卡巴唑：醇络合物在乙醇溶液和稀非质子溶剂中的光诱导双质子转移反应。大部分工作将使用时间分辨荧光测量。溶质的物理化学性质受溶液环境的影响很大。溶剂对化学反应的影响以及溶液中发生的动力学过程已被广泛研究。这项研究表明，溶剂不是提供一种发生物理和化学过程的惰性和静态介质，而是通常在这些过程中起着活跃和关键的作用。由Moog进行的研究将专门针对了解分子间氢键在溶液中的溶质反应性和动力学中所起的作用。***

9303817 Moog Richard S. Moog is supported by a grant from the Theoretical and Computational Chemistry Program to perform condensed phase spectroscopic studies. Two lines of research will be pursued. The first study will compare the rotational reorientation of Coumarin 102 dye in non-polar decalin with the reorientation lifetime in fluorinated alcohols to see what the effects of hydrogen bonding are on the reorientation times. The second study will examine the photoinduced double proton transfer reaction of hydrogen bonded 1-azacarbazole : alcohol complexes in alcohol solutions and in dilute aprotic solvents. Most of the work will employ time resolved fluorescence measurements. %%% The physical and chemical properties of solutes are profoundly influenced by the solution environment. The influence of solvent on chemical reactions and the dynamical processes which occur in solution have been widely investigated. This research has shown that, rather than providing an inert and static medium in which physical and chemical processes occur, the solvent often plays an active and crucial role in these processes. The investigvations to be performed by Moog will be specifically directed at understanding the role which intermolecular hydrogen bonding plays in solute reactivity and dynamics in solution. ***
