  摘要：

  已经表明，含有p - N , N - 二烷基氨基亚苄基氰基乙酸酯基序的化合物可以用作荧光非机械粘度传感器。这些被称为分子转子的化合物属于一类荧光探针，已知它们在激发态会形成扭曲的分子内电荷转移复合物。在这项研究中，我们介绍了这些化合物作为粘度传感器的合成和光谱表征。讨论了这些转子的分子结构和电子密度对发射波长、荧光强度和粘度敏感性的影响。

  公开（公告）日：2006-04-13

  A method for detecting local shear stress values using molecular rotors that allows for an extremely sensitive determination of a shear stress field or a flow field, even at very low flow rates. In one embodiment, molecular rotors may be adhered to a fiber optic probe or other solid surface, and the fluorescence emission of those molecular rotors may be probed at a location of the fiber optic probe tip or other solid surface. In another preferred embodiment, rotors may be adhered to another solid surface, such as any glass or polymer substrate that may be pre-functionalized (e.g., quartz, polystyrene or silicate glass) to create a probe that may then be used for in vivo as well as in vitro viscosity measurements. In another embodiment, molecular rotors may be dissolved in a target solution, and emission intensity obtained by one of several techniques.
