摘要
利用稳态荧光去极化和时间相关单光子计数技术，研究了非极性探针 3-(苯并[d]噻唑-2-基)-7-(二乙基氨基)-2 H-色烯-2-酮（3BT7D2H-one）在正戊醇、正壬醇和正癸醇溶剂中的旋转动力学。实验观察表明，与其他所选溶剂相比，3BT7D2H-one 在正癸醇溶剂中的旋转速度较慢。旋转运动采用斯托克-爱因斯坦-德贝（SED）模型进行分析。在所有三种溶剂中，3BT7D2H-one 溶质的旋转动力学都能通过 SED 滑动边界极限得到满意的描述。
Temperature-dependent Rotational Dynamics of a 3-(benzo[d]Thiazol-2-yl)-7-diethylamino)-2 H-chromen-2-one non-polar Probe in n-pentanol, n-nonanol, and n-decanol Solvents.
Rotational dynamics of non-polar probe 3-(benzo[d]thiazol-2-yl)-7-(diethylamino)-2 H-chromen-2-one (3BT7D2H-one) and in n-pentanol, n-nonanol, and n-decanol alcohol solvents is studied using steady-state fluorescence depolarization and time-correlated single photon counting technique with varying temperature. Experimental observations indicate that 3BT7D2H-one rotates slowly in n-decanol solvent compared to other chosen solvents. Rotational motion is analyzed using the Stoke 's-Einstein-Debye (SED) model. 3BT7D2H-one solute rotational dynamics is satisfactorily described by the SED slip boundary limit in all three solvents.
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.
