The spectral-luminescent properties of fluorescent probe laurdan (6-dodecanoyl-2-dimethylaminonaphthalene) in homogeneous solvents of different chemical natures and water-micellar solutions (WMS) of non-ionic Triton Х-100 surfactant are investigated. The relative contributions of the basicity and acidity parameters of the solvents to the laurdan fluorescence band shift are estimated. The use of the water-micellar solution of Triton Х-100 as a solvent leads to a considerable change of the fluorescent laurdan properties: occurrence of a new fluorescence band and absence of hydrogen bonding of the laurdan carbonyl group with water molecules. The physical and chemical properties of the Triton Х-100 solvent and the polarity of laurdan surroundings in WMS are estimated.

月桂醇在均相溶剂和水胶束溶液中的荧光

研究了荧光探针月桂醇（6-十二烷酰基-2-二甲氨基萘）在不同化学性质的均相溶剂和非离子 Triton Х-100 表面活性剂的水胶束溶液 (WMS) 中的光谱发光特性。估计溶剂的碱度和酸度参数对劳丹荧光带位移的相对贡献。使用 Triton Х-100 的水胶束溶液作为溶剂会导致荧光 laurdan 特性发生相当大的变化：出现新的荧光带，并且 laurdan 羰基与水分子之间没有氢键。估计了 Triton Х-100 溶剂的物理和化学性质以及 WMS 中 laurdan 周围环境的极性。
