Time-resolved laser spectroscopy of reactive and nonreactive processes in ionic liquids and their mixtures with carbon dioxide

非反应和反应动力学的分子在离子液体中，离子液体混合物和在半导体-离子液体界面将研究飞秒毫秒瞬态宽带吸收和荧光光谱，以阐明在这些介质中的不同类型的溶质-溶剂相互作用的重要性。类胡萝卜素、喹诺酮、邻苯二甲酰亚胺和吲哚啉将被用作离子液体溶剂化动力学、微极性和氢键的报告分子。纯离子液体及其混合物的影响将研究模型反应，如吲哚啉和噻唑啉衍生物的光异构化，电子转移过程中涉及吲哚啉染料附着到ZnO表面用于染料敏化太阳能电池，和选定的自由基组合反应。

Nonreactive and reactive dynamics of molecules in ionic liquids, ionic liquid mixtures and at the semiconductor - ionic liquid interface will be investigated by femtosecond to millisecond transient broadband absorption and fluorescence spectroscopy to elucidate the importance of the different types of solute-solvent interactions in these media. Carotenoids, a quinolone, phthalimide, and indolines will be used as reporter molecules for ionic liquid solvation dynamics, micropolarity and hydrogen-bonding. The influence of neat ionic liquids and their mixtures will be studied for model reactions, such as the photoisomerization of indoline and thiazoline derivatives, electron transfer processes involving indoline dyes attached to ZnO surfaces used in dye-sensitized solar cells, and selected radical combination reactions.
