摘要：To establish a new strategy for the development of fluorescent viscosity sensors by the principle of photoinduced electron transfer, three 4-aminonaphthalimide based D-(CH2)(2)-A molecules were designed and synthesized. The effects of solvent polarity and viscosity on the fluorescence spectra of these compounds were investigated. These compounds exhibit viscosity-sensitive fluorescence spectra in ethylene glycol-glycerol mixtures. A mechanism about exciplex formation was proposed to explain their viscosity sensitivity.
