摘要

研究了 3-(苯并[d]噻唑-2-基)-7-(二乙基氨基)-2 H-色烯-2-酮（3BT7D2H-one）在丙酮和乙酸乙酯两种非极性溶剂中不同温度下的旋转动力学。在醋酸乙酯溶剂中，旋转动力学遵循斯托克-爱因斯坦-德贝（SED）模型，但在丙酮溶剂中，当温度升高时，旋转动力学出现偏差。对准流体动力学模型 Gierer 和 Wirtz（GW）模型以及 Dote-Kivelson Schwartz（DKS）模型进行了定性研究。

Effect of Temperature on Rotational Dynamics of 3BT7D2H-one in Acetone and Ethyl Acetate Solvents.

The rotational dynamics of 3-(benzo[d]thiazol-2-yl)-7-(diethylamino)-2 H-chromen-2-one (3BT7D2H-one) in two non-polar solvents acetone and ethyl acetate have been studied with varying temperatures. The rotational dynamics follow follows the Stoke's-Einstein-Debye (SED) model in ethyl acetate solvent but shows deviation in acetone solvent when temperature is increased. Quasi-hydrodynamic models Gierer and Wirtz (GW) model and Dote-Kivelson Schwartz (DKS) is studied in a qualitatively way.

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
