synthesized and their absorption and fluorescence properties were recorded in solvents of varying polarity. Spectroscopic studies reveal that, the solvatochromic behavior of the compounds depend not only on the polarity but also on the hydrogen-bonding properties of the solvents. The effects of β-cyclodextrin on the fluorescence properties of both compounds were studied. It was found that there is an enhancement
合成了3-萘基-1-苯基-5-(5-氟-2-硝基苯基)-2-吡唑啉(NPFP),一种荧光探针及其衍生物NPFP-去氧肾上腺素,并在各种溶剂中记录了它们的吸收和荧光性质极性。光谱研究表明,化合物的溶剂变色行为不仅取决于极性,还取决于溶剂的氢键性质。研究了β-环糊精对两种化合物荧光性质的影响。发现在β-环糊精存在下标记药物(NPFP-去氧肾上腺素)的荧光强度增强。在本研究中,已通过荧光技术以稳态和时间分辨模式研究了嵌入在β-环糊精腔中的NPFP-去氧肾上腺素的分子运动。
